[See Yester.]

1. The day last past; the day next before the present.

All our yesterdays have lighted fools the way to dusty death.

We are but of yesterday, and know nothing. Job 8:9.

2. Yesterday is used generally without a preposition; as, I went to town yesterday. Yesterday we received letters from our friends. In this ease, a preposition is understood; as on yesterday, or during yesterday. The word may be considered as adverbially used.
