etymonline
attain (v.)
c. 1300, "succeed in reaching, come so near as to touch," from ataign-, stem of Old French ataindre "to come up to, reach, attain, endeavor, strive" (11c., Modern French atteindre), from Vulgar Latin *attangere, corresponding to Latin attingere "to touch; arrive at," from ad "to" (see ad-) + tangere "to touch," from PIE root *tag- "to touch, handle." 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.
