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.

sĭlentĭōsus, a, um, adj. [silentium], perfectly still or silent: nactus opacae noctis silentiosa secreta, App. M. 11 init.
Adv.:
sĭlentĭōsē, stilly, silently: silentiose geritur publicum bonum, Cassiod. Var. 11, 1 med.
