The original meaning seems to have been, to let loose, let go, let drop. Cf. Alas, Late, Lassitude, Let to hinder.]

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.
