Word Origin

• late Middle English (in the adjectival sense ‘close, similar’): from late Latin approximatus, past participle of approximare, from ad- ‘to’ + proximus ‘very near’. The verb (originally meaning ‘bring close’) arose in the mid 17th cent.; the current use as an adjective dates from the early 19th cent.
