incubate
Incubate (verb) means to keep eggs, organisms or living tissue under the right environmental conditions in order to hatch, grow or sustain them.
Etymology
First attested in 1641; borrowed from Latin incubātus, an alternative to incubitus, perfect passive participle of incubō (“to hatch”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from in- (“in”) + cubō (“to lie”).
