词源

词源 1
First attested in 1599, from Latin excavātus (“hollowed out”), perfect passive participle of excavō (“to hollow out”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from ex (“out”) + cavō (“to hollow out, pierce”), from cavus (“cave, hole”) + -ō (verb-forming suffix). Participial usage up until Early Modern English.
词源 2
From a substantivization of Latin excavātus through the associated taxon's name (Excavata), see -ate (noun-forming suffix) and Etymology 1 for more.
