This case presents the question whether actual costs can be awarded pursuant to MCR 2.405(D) in a case that has been decided by summary disposition. The circuit court awarded such costs, and the Court of Appeals affirmed. We reverse, because the plain language of the court rule precludes such an award.

The plaintiffs own a dairy farm in Kent County. In 1977, they purchased an automated milking system. In the early 1980s, the plaintiffs determined that their herd was experiencing major health and production problems.
The plaintiffs filed this suit in October 1985. The defendants are the manufacturer of the automated milking system, the installer of the system, and the utility that supplied electrical service to the farm. The plaintiffs have alleged that each defendant played a role in causing the harm. In 1986, the plaintiffs amended their complaint so that it accurately named the manufacturer and the installer.
In March 1988, the installer filed an offer of judgment pursuant to MCR 2.405(B). He offered to settle the case, if the plaintiffs would accept $101 as complete payment for all liability. Approximately three weeks later, the plaintiffs rejected this offer.
The manufacturer and the utility filed similar *516offers in May 1988. Each offered to settle the case for $100. Again, the plaintiffs declined the offers.1
In June 1988, each defendant filed a motion for summary disposition on the ground that the plaintiffs’ suit had not been filed within the statutory limitation period. MCR 2.116(C)(7). Following a hearing, the circuit court granted the motions for summary disposition and entered an order dismissing the case.
Following the entry of the order granting summary disposition, the manufacturer and the installer filed motions seeking the actual costs that they had incurred following the plaintiffs’ rejection of their offers to settle. This motion for actual costs2 was filed under MCR 2.405(D), which provides:
Imposition of Costs Following Rejection of Offer. If an offer is rejected, costs are payable as follows:
(1) If the adjusted verdict is more favorable to the offeror than the average offer, the offeree must pay to the offeror the offeror’s actual costs incurred in the prosecution or defense of the action.
(2) If the adjusted verdict is more favorable to the offeree than the average offer, the offeror must pay to the offeree the offeree’s actual costs incurred in the prosecution or defense of the action. However, an offeree who has not made a counteroffer may not recover actual costs.
(3) The court shall determine the actual costs *517incurred. The court may, in the interest of justice, refuse to award an attorney fee under this rule.
(4) Evidence of an offer is admissible only in a proceeding to determine costs.
(5) Proceedings under this rule do not affect a contract or relationship between a party and his or her attorney.
A request for costs under this subrule must be filed and served within 28 days after the entry of the judgment or entry of an order denying a timely motion for a new trial or to set aside the judgment.
The motions filed by the manufacturer and the installer were separately heard and granted.3
The plaintiffs appealed the summary disposition, as well as the orders that granted actual costs to the manufacturer and to the installer. The Court of Appeals consolidated these separate appeals. It later affirmed the summary disposition in favor of the utility and the installer, but vacated the summary disposition that had entered in favor of the manufacturer.4 The award of actual costs to the installer was affirmed but, since the summary disposition in favor of the manufacturer had been set aside, the court also vacated the award of actual costs in favor of the manufacturer.5
The plaintiffs have applied for leave to appeal the judgment of the Court of Appeals, insofar as it affirmed the judgments of the circuit court.6_

The plaintiffs appeal the award of actual costs in favor of the installer. They observe that actual costs are to be paid only where there has been a "verdict.” MCR 2.405(D)(1). Further, the rule contains a clear definition of the term "verdict”:
"Verdict” means the award rendered by a jury or by the court sitting without a jury, excluding all costs and interest. [MCR 2.405(A)(4).]
Since the present case was decided by summary disposition, and not as a result of an "award rendered by a jury or by the court sitting without a jury,” the plaintiffs believe that the rule does not authorize an award of actual costs.
The Court of Appeals rejected the argument, observing that an adjacent court rule, which governs mediation, provides that a " 'verdict’ ” includes " 'a judgment entered as a result of a ruling on a motion filed after mediation.’ ” MCR 2.403(O)(2)(c). The Court of Appeals agreed with a commentary7 that suggested that the definition of "verdict” found in MCR 2.403(C)(2)(c) be applied in both rules, notwithstanding the definition found in MCR 2.405(A)(4).
The Court of Appeals thus concluded that "a judgment resulting from a grant of summary disposition is a verdict for purposes of imposing sanctions pursuant to MCR 2.405.” The Court added that such an interpretation of the rule "is consistent with furthering its intended purposes of encouraging settlements and avoiding protracted litigation.”_
*519in
MCR 2.403 is a detailed rule that governs the complicated and controversial area of mediation. The rule is written with great specificity. One must, therefore, observe that MCR 2.403(O)(2) provides that the rule’s definition of "verdict” applies "[f]or the purpose of this rule.”
The rules in question, MCR 2.403(0) and 2.405(D), contain precisely worded definitions of "verdict.” These definitions are clear, and there is no sound reason to employ one rule’s definition in the application of the other rule.8 The term "verdict” in MCR 2.405(D) should be interpreted in accordance with the explicit definition found in MCR 2.405(A)(4). That definition of "verdict” does not include a summary disposition.9
Accordingly, we conclude that the circuit court and the Court of Appeals erred, and that the award of actual costs in favor of the installer must *520be set aside.10 In lieu of granting leave to appeal, we therefore reverse in part the judgments of the Court of Appeals and the Oakland Circuit Court.11 MCR 7.302(F)(1).
