c.1300, “to succeed in reaching,” from stem of Old French ataindre (11c., Modern French atteindre) “to come up to, reach, attain, endeavor, strive,” from Vulgar Latin *adtangere, from Latin attingere “to touch, to arrive at,” from ad- “to” (see ad-) + tangere “to touch” (see tangent). Latin attingere had a wide range of meanings, including “to attack, to strike, to appropriate, to manage,” all somehow suggested by the literal sense “to touch.” Related: Attained; attaining.
