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 century; the current adjectival sense dates from the early 19th century.
