The original meaning seems to have been, to let loose, let go, let drop. Cf. {Alas}, {Late}, {Lassitude}, {Let} to hinder.] 1. To leave; to relinquish; to abandon.

Note: The active form of the infinitive of let, as of many other English verbs, is often used in a passive sense; as, a house to let (i. e., for letting, or to be let). This form of expression conforms to the use of the Anglo-Saxon gerund with to (dative infinitive) which was commonly so employed. See {Gerund}, 2. `` Your elegant house in Harley Street is to let.'' --Thackeray. In the imperative mood, before the first person plural, let has a hortative force. `` Rise up, let us go.'' --Mark xiv. 42. `` Let us seek out some desolate shade.'' --Shak. [1913 Webster]
