Note 125.1 — Front matter (continued 3)

ves = ve, go. This colloquial form of the imperative is parallel to the French forms in-s of the first conj., found before en and y, e.g. donnes-en, vas-y. The form vas is even found under the same condition as here, viz. before the preposition à, e.g. vas à la veillée, Mérimée, Colomba, C. XII. Indicative influence is the usual explanation.
