This is an original proceeding in mandamus. The petitioners are six homeless residents of the City of Charleston.1 The respondent is Leon Ginsberg, Commissioner of the West Virginia Department of Welfare. The petitioners seek to compel the respondent to provide adult protective services to incapacitated individuals such as themselves and others similarly situated. We find that the petitioners are entitled to such relief, and grant the writ.
The individual petitioners are all persons within the state of West Virginia who lack the means to maintain a permanent residence, and who therefore are often forced to spend their days and nights on public streets, alleys, riverbanks, and other various outdoor locations. The petitioners claim that the Commissioner of the Department of Welfare has a statutory and constitutional duty to provide emergency shelter to enable them and similarly situated persons to adequately sustain life and reasonable health.
The petitioners’ statutory claim is based upon the provisions of W.Va.Code §§ 9-6-1 through 9-6-8 (Cum.Supp.1982), the Social Services For Adults Act. The Act is designed to provide protective services to incapacitated adults. See generally W.Va. Code § 9-6-2. Specifically, W.Va.Code § 9-6-7 provides:
The department may develop a plan for a comprehensive system of adult protective services including social case work, medical and psychiatric services, home care, day care, counseling, research and others.
It shall offer such services as are available and appropriate in the circumstances to persons who, other than for compensation, have or intend to have the actual, physical custody and control of an incapacitated adult and to such incapacitated adults or to adults who may request and be entitled to such protective services _
An “incapacitated adult” is defined by the Act as “any person who by reason of physical, mental or other infirmity is unable to independently carry on the daily activities of life necessary to sustaining life and reasonable health.” W.Va.Code § 9-6-l(4). The Department of Welfare is authorized to institute proceedings to abate any abuse or neglect of an incapacitated adult or to abate an emergency situation. W.Va.Code § 9-6-4. An “emergency situation” is defined as “a situation or set of circumstances which presents a substantial and immediate risk of death or serious permanent injury to an incapacitated adult.” W.Va.Code § 9-6-l(5). The petitioners claim that they are incapacitated adults who are entitled to protective services under the provisions of the Act.
We note initially that if the petitioners are members of the class which the Social Services For Adults Act is designed to benefit, they possess a constitutional right to the relief which they seek under Article III, Section 10 of the West Virginia Constitution. As we stated in Syllabus Point 1 of Cooper v. Gwinn, 171 W.Va. 245, 298 S.E.2d 781 (1981): “Inherent in the republican form of government established by our State Constitution is a concept of due process that insures that the people *20receive the benefit of legislative enactments.” Our inquiry therefore focuses on whether the petitioners are entitled to relief under the Act.
The respondent advances two principal arguments in opposition to the petitioners’ claim for relief. First, the respondent contends that the petitioners are not “incapacitated adults”, within the meaning of the Act. In this regard the respondent argues that the Act is in derogation of the common law, and therefore should be strictly construed against the petitioners. Second, the respondent contends that the provision of protective services under the Act is discretionary, precluding relief by mandamus. We find no merit in these contentions.
The Department of Welfare is a creation of the Legislature, and has as its express purpose the provision of welfare assistance programs “to the end that residents of the State who are subject to the recurring misfortunes of life may continue to have such aid and encouragement as the county alone, the State alone or the State in cooperation with the federal government may provide.” W.Va.Code § 9-1-1 (1979 Replacement Vol.). The Department of Welfare has the responsibility of administering welfare assistance programs and possesses “all powers, not inconsistent with state law, as may be necessary for the disbursement and distribution of welfare assistance to those persons qualified therefor in as prompt, fair, orderly, efficient and economical manner as possible.” W.Va.Code § 9-2-5 (1979 Replacement Vol.). The Commissioner of the Department of Welfare is the “chief executive officer and administrative head of the department,” W.Va.Code § 9-2-2 (1979 Replacement Vol.), who is charged with the “powers, duties and responsibilities granted and assigned to that office ... by law -” W.Va.Code § 9-2-6 (1979 Replacement Vol.). The Commissioner has specific authority and power to “[establish and maintain such institutions as are necessary for the temporary care, maintenance, and training of children and other persons.” W.Va.Code § 9-2-6(9).
One of the primary goals of the Department of Welfare is to provide aid to indigent persons. An “indigent person” is “any person who is domiciled in this State and who is actually in need as defined by department rules and regulations and has not sufficient income or other resources to provide for such need as determined by the department.” W.Va.Code § 9-l-2(g) (1979 Replacement Vol.). Qualified indigent persons who apply for assistance “shall be granted state assistance in such form and amount, to such extent, and for such period, as authorized by applicable state laws, rules and regulations of the department and as determined by the department in accordance with such laws, rules and regulations and within limits of available funds.” W.Va.Code § 9-3-2 (1979 Replacement Vol.); see also W.Va.Code § 9-3-1 (1979 Replacement Vol.).
On April 11, 1981, the Legislature amended chapter nine of the West Virginia Code by adding thereto a new article. See 1981 W.Va.Acts ch. 215. The amendment authorized the Department of Welfare to provide social services for adults; established a comprehensive protective service system; and provided for the promulgation of rules and regulations allowing for payment of services to incapacitated persons as defined in the amendment. Id. The amendment is now found at W.Va.Code §§ 9-6-1 through 9-6-8, and is titled “Social Services For Adults.”
In accordance with the Legislature’s directions, see W.Va.Code § 9-6-2, the Commissioner of the Department of Welfare promulgated regulations on August 14, 1981, implementing the Social Services For Adults Act. See W.Va.Dept. of Welfare, Social Services Manual, ch. 29 (1981). Regulation 29010 defines protective services as “casework, treatment and crisis intervention services provided to adults in hazardous situations who, due to physical and/or mental incapacities, are no longer able to care for their basic needs and who have no one else able or willing to do so.” Regulation 29010 further states that the goal of adult protective services is to remedy “neglect, abuse, or exploitation.” “Adult neglect” is defined as:
*21the failure to provide adequate food, ... shelter or medical care ... to an individual who is unable to independently carry on the daily activities of life necessary for maintaining and sustaining a healthful existence. This does not necessarily imply the involvement of another person. When an individual’s capacity for self care and management of his own activities of daily living is impaired because of physical or mental handicaps, he may be responsible for self neglect.
W.Va.Dept. of Welfare, Social Services Manual, Reg. 29010C.
The regulations further indicate that valid reasons for providing adult protective services include circumstances where “[t]he individual has been evicted or has inadequate or unsafe housing,” or where “[t]he individual has been deprived of adequate food or shelter_” W.Va.Dept. of Welfare, Social Services Manual, Reg. 29100. Adult protective service clients are defined by the regulations as persons meeting the following criteria:
A. The client will have a serious impairment in physical or mental functioning. ...
B. The client is functionally disabled in regard to activities of daily living. ...
C. The client must be 18 years or older and must reside in the community rather than in an institution or nursing home....
D. The client is alone or without a family member, friend or interested party able and willing to provide the necessary support to alleviate the presenting problem.
E. The client is in danger of being harmed (through action or inaction by another individual or through his own actions) without intervention at this time. A client may meet the first four characteristics and still manage to function for quite some time. However, in order to classify a case as protective, a precipitating factor (a medical, psychiatric, or social emergency) must exist. If intervention does not occur at this time, serious consequences (death, physical or mental injury, neglect or maltreatment, failure to receive adequate food, shelter or clothing, deprivation of entitlements, wasting of resources, loss of property or funds, inappropriate relocation) will result.
W.Va.Dept. of Welfare, Social Services Manual, Reg. 29020 (emphasis in original).
The respondent contends that the petitioners are not qualified to receive adult protective services because they do not suffer from physical or mental infirmities as required by the department’s regulations. The petitioners, on the other hand, argue that the regulations are unduly restrictive and do not comply with the law enacted by the Legislature.
The Social Services For Adults Act defines “incapacitated adult” as “any person who by reason of physical, mental or other infirmity is unable to independently carry on the daily activities of life necessary to sustaining life and reasonable health.” W.Va.Code § 9-6-l(4) (emphasis added). The term “infirmity” is not defined by the Act. Generally, “[i]n the absence of any specific indication to the contrary, words used in a statute will be given their common, ordinary and accepted meanings.” Syllabus Point 1, Thomas v. Firestone Tire & Rubber Co., 164 W.Va. 763, 266 S.E.2d 905 (1980); Syllabus Point 1, Tug Valley Recovery Center v. Mingo County Commission, 164 W.Va. 94, 261 S.E.2d 165 (1979).
Webster’s Third New International Dictionary (1970) defines “infirmity” as “the quality or state of being infirm”; “an unsound unhealthy or debilitated state”; “a defect of personality or weakness of the will.” “Infirm” is defined as “not strong or sound physically”; “of poor or deteriorated vitality especially as a result of age”; “weak of mind, will or character”; “not solid or stable.” It is clear from these commonly accepted definitions that the term “infirmity” contained in W.Va.Code § 9-6-l(4) encompasses more than the serious physical or mental impairments to which the term is limited by the Department of Welfare’s regulations. See W.Va. *22Dept, of Welfare, Social Services Manual, Reg. 29020A.
Contrary to the respondent’s representations, the Social Services For Adults Act is clearly remedial legislation which should be construed to achieve its beneficial purposes. See, e.g., Gibson v. Rutledge, 171 W.Va. 164, 298 S.E.2d 137 (1982); Andy Bros. Tire Co., Inc. v. West Virginia State Tax Comm’r, 160 W.Va. 144, 233 S.E.2d 134 (1977). The purpose of the Department of Welfare is to provide aid and encouragement to the “residents of the State who are subject to the recurring misfortunes of life_” W.Va.Code § 9-1-1. When the definition of “incapacitated adult” contained in W.Va.Code § 9-6-l(4) is read in light of this legislative purpose, it is evident that the Legislature intended a broader application of the statute than that given it by the respondent.
While it is true that the interpretation of a statute by the agency charged with its administration should ordinarily be afforded deference, see, e.g., Security National Bank and Trust Co. v. First West Virginia Bancorp, Inc., 166 W.Va. 775, 277 S.E.2d 613 (1981), when that interpretation is unduly restrictive and in conflict with the legislative intent, the agency’s interpretation is inapplicable. See, e.g., Harrison v. Ginsberg, 169 W.Va. 162, 286 S.E.2d 276 (1982); see also Townsend v. Swank, 404 U.S. 282, 92 S.Ct. 502, 30 L.Ed.2d 448 (1971).
We therefore conclude that the term “incapacitated adult” contained in W.Va. Code § 9-6-1 was intended by the Legislature to encompass indigent persons like the petitioners, who, by reason of the recurring misfortunes of life, are unable to independently carry on the daily activities of life necessary to sustaining life and reasonable health.
The respondent’s remaining contention is that the provision of adult protective services pursuant to the Social Services For Adults Act is discretionary with the Department of Welfare, and therefore mandamus is an inappropriate remedy. In support of his contention the respondent cites the language of W.Va.Code § 9-6-7 which provides that the Department of Health “may develop a plan for a comprehensive system of adult protective services _” (emphasis added). We agree with the respondent that the use of the word “may” in a statute often indicates discretion. See, e.g., cases collected at 26A Words and Phrases 82-86 (Cum.Supp. 1982); but see Trail v. Trail, 56 W.Va. 594, 49 S.E. 431 (1904) (when the word may is in a statute made for the benefit of persons it is not permissive, but mandatory or compulsory). However, the statute relied upon by the respondent further provides that any plan developed by the Department of Welfare “shall offer such services as are available and appropriate in the circumstances ... to adults who may request and be entitled to such protective services _” W.Va.Code § 9-6-7 (emphasis added). “It is well established that the word ‘shall,’ in the absence of language in the statute showing a contrary intent on the part of the Legislature, should be afforded a mandatory connotation.” Syllabus Point 1, Nelson v. Public Employees Insurance Board, 171 W.Va. 445, 300 S.E.2d 86 (1982). Thus, the plan which the Department of Welfare has developed, see W.Va. Dept. of Welfare, Social Services Manual, ch. 29, must offer such adult protective services “as are available and appropriate in the circumstances .... ”
The respondent further argues that the language of W.Va.Code § 9-6-2 evidences the legislative intent that the provision of adult protective services is discretionary with the Department of Welfare. The pertinent language of the statute provides that the Commissioner of the Department of Welfare shall promulgate regulations to implement the goals of the statute “to the extent that the Commissioner believes feasible under the provisions of this article within the state appropriations and other funds available ....” W.Va.Code § 9-6-2 (emphasis added). We agree that this language grants the respondent discretion in the drafting of regula*23tions to implement the goals of the Act.2
However, the respondent has exercised his discretion in the promulgation of regulations found at Chapter 29 of the Department of Welfare’s Social Services Manual. These regulations establish the duty of the department to provide assistance to incapacitated adults who are the victims of neglect, abuse, or exploitation. See W.Va. Dept, of Welfare, Social Services Manual, Regs. 29010; 29100; 29120. The Commissioner therefore has a duty to provide assistance to those petitioners who meet these criteria. The assistance provided must be such as “will meet the individual’s needs with the least necessary restrictions on his liberty and civil rights.” W.Va. Dept, of Welfare, Social Services Manual, Reg. 29120.
The petitioners are individuals who are unable to provide for themselves adequate shelter necessary to sustain life and reasonable health. They seek adult protective services in the form of shelter, food and medical care as incapacitated adults from the Department of Welfare. The lack of shelter, food and medical care which poses a substantial and immediate risk of death or serious permanent injury to an incapacitated adult is a valid reason for intervention by the Department of Welfare through the provision of adult protective services. W.Va.Code § 9-6-l(5); W.Va. Dept, of Welfare, Social Services Manual, Regs. 29020; 29100. The department is required to provide such services as are “appropriate in the circumstances,” W.Va. Code § 9-6-7, and which “meet the individual’s needs.” W.Va.Dept. of Welfare, Social Services Manual, Reg. 29120.
Accordingly, we grant the writ of mandamus directing the Commissioner of the Department of Welfare to provide emergency shelter, food and medical care to the petitioners and other similarly situated persons as required by W.Va.Code §§ 9-6-1 through 9-6-8 and Chapter 29 of the Department of Welfare’s Social Services Manual.
Writ granted.
