Etymology

First attested in the early 15ᵗʰ century, in Middle English; Middle English assimilaten (“to become similar; to make like”), from assimilat(e) (“assimilated”, also used as the past participal of assimilaten) + -en (verb-forming suffix), borrowed from Late Latin assimilātus, variant of Latin assimulātus (“made similar, imitated”), perfect passive participle of assimulō (see -ate (verb-forming suffix)), from ad + simulō (“to imitate, copy”), from similis (“like, similar”), ultimately from Proto-Indo-European *sem- (“together, one”). Doublet of assemble.
