Etymology

It is inherited from Middle English ajusten, borrowed from Old French ajoster (“to add, assemble, calibrate”), ajuster,[2][3] from Vulgar Latin *adjuxtāre, to bring near,[2][3] from Latin ad-, to, and juxtā, near, close by (from the PIE root of yoke).[3][2][4] In the 16th century French refashioned it as adjuster, as if from juste, right (see just),[2][3][5] and English reborrowed the word in that form before 1611;[2] modern French has ajouter, to add.[3]

Earliest recorded meaning

To correct, remedy: about 1380, in Chaucer's translation of Boethius.[2][3]

Semantic evolution

In the reborrowed form, the OED's first sense, to arrange, settle or harmonize things that differ, is from 1611.[6] To arrange something suitably in relation to something else is from 1664,[6] and to settle a claim in insurance from 1755.[6] To adapt oneself or get used to something is from 1924,[6] and it also means to achieve psychological balance.[7]
