English approximate
From Middle English approximat(e) (“close, near (to); similar; intimate”, also used as the past participle of approximaten), from Latin approximātus, the perfect passive participle of approximō (see -ate (adjective-forming suffix)), further from ad- (“to, towards, at”) + proximō (“to come near”). The noun was derived from the adjective through substantivization, see -ate (noun-forming suffix). See also proximate. By surface analysis, ap- + proximate.
