Ellipsis means the omission of part of a grammatical construct. This is done either because the omitted information would be understood from contextual clues or because there is no need to repeat the same information twice. For example, in the following conversation, B’s response uses ellipsis and “おなかがすいた” is elided after “私も.”

A: おなかがすいた。 (I am hungry.)
B: 私も。 (Me too.)
