Linguistic Origin & Historical Etymology

Derived from the Latin 'concretus', the past participle of 'concrescere' meaning 'to grow together' or 'to harden', from 'com-' (together) + 'crescere' (to grow). It entered English in the late 15th century initially as an adjective denoting something formed by the coalescence of separate particles into one body.
