pavid \PAEV-id\ (adjective) - Easily frightened, fearful, pusillanimous, timorous.
"Lana Issacs in accounting is such a pavid lamb, she will never ask for a raise."
The etymology of today's word doesn't run very deep. It is a thinly veiled copy of Latin pavidus "fearful" from pavere "to quake with fear." The root here is the same found in putare "to cleanse, think over, reflect," found in "compute," "repute," "dispute," and others. Other relatives have long since dissipated.
