Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

passercŭlus, i, m. dim. [1. passer], a little sparrow, sparrowlet, Cic. Div. 2, 30, 65.
As a term of endearment: dic me igitur tuum passerculum, Plaut. As. 3, 3, 76.
