(“to approach, come near to”), from Latin ad- (prefix meaning ‘to’) + propi? (“to draw near”) (from prope (“near, nearby”), ultimately from Proto-Indo-European *pro- (a variant of *per- (“before, in front; first”)) + *-k?e (“suffix forming distributives from interrogatives”)).

Usage notes

Regarding the use of sense 5 (“to come near to (someone or something) in place, time, character, or value”) in discussing convergence in mathematical analysis, modern rigorous formulations avoid using the words approach and converge. However, the terms are used informally when rigour is not required.
