IMPERIAL

(Fr.) In Architecture, a species of dome whose profile is pointed towards the top and widens towards the base, thus forming a curve cf contrary flexure. IMPERSONAL VERBS, in Grammar, are those used only in the third person; as elsurt, licet, it is lawful. It is quite clear that every verb, whether active or pa ive, must have a nece ary reference to some noun, either expre ed or understood, for its nominative,- and hence the doctrine of Impersonal verbs has been justly rejected by the best grammarians,both ancient and modern. See Grammar. [s. 606]
