词源

The adjective is first attested in 1425, in Middle English, the verb in 1538; from Middle English perforat(e) (“perforated, pierced”), borrowed from Latin perforātus, the perfect passive participle of perforō (“to bore or pierce through, to perforate”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from per- (“through, thorough”) + forō (“to bore, pierce”). Participial usage of the adjective up until Early Modern English.
