1. To glance, look, or stare out (from something or someplace) toward someone or something. I looked inside of the box and saw a small kitten peering out at me. We peered out from the window at the tanks passing through the streets.

2. To be or become partially visible to someone or something (from behind or beneath something). The moon peered out at us from behind the clouds. From behind the black paint, some splotches of the mural's color still peers out at the city streets.
