detach

Etymology

It is borrowed from French détacher (“to detach, untie”),^{[2][3][4][5][6]} earlier destacher,^[2][7][8] from Old French destachier, recorded from the 12th century.^[2][3][5] Most dictionaries analyse this as des- (“apart”), from Latin dis-, and attachier (“to attach”),^{[3][4][5][6][9]} while the OED, Klein and Skeat take the second part as tache (“nail, hook”).^[2][10][11] Partridge takes that word as a shortened form of estache (“a stake”),^[12] and Ayto and Etymonline derive the French base of attach from Proto-Germanic *stakōn (“a stake”).^[13][4] The OED compares Spanish destacar and Italian distaccare,^[2] and Klein compares Italian staccato.^[10] Caxton used a form distache with the prefix of Old French, but according to the OED the present word appears to have been adopted from modern French late in the 17th century.^[2][14] Barnhart adds that it may be a back-formation from detachment, recorded from 1669, since the first record is military.^[3]

Earliest recorded meaning

To separate and send off a part of a military body for a special purpose: 1684, in Scanderbeg Redivivus.^[2][3] The general sense follows in 1686, in Spence's translation of Varillas.^[2][6] Etymonline dates the word to the 1680s,^[4] and the Shorter Oxford and the Oxford Dictionary of English record it earlier, in the late 16th century, in the sense "to discharge a gun".^[7][15]

Semantic evolution

The word entered English as a military and naval term, for sending a regiment, a ship or the like on a special mission,^[2][3] and the general sense of unfastening and separating, literal and figurative, appeared at almost the same time.^[2][4] Johnson (1755) gives both, "to separate; to disengage" and "to send out part of a greater body of men on an expedition".^[16] The intransitive use, of becoming disconnected or separating oneself, is recorded from 1842, in Tennyson.^[2][7] The adjective detachable dates from 1818.^[3][17]
