conform

Etymology

It is inherited from Middle English conformen, also confourmen,^[2][3][4] borrowed from Old French conformer (“to make or be similar, agree”),^[5][3][4][6] and directly borrowed from Latin cōnfōrmō (“to form, fashion, shape symmetrically”),^[3][4][7][8] from com- (“with, together”) and fōrmō (“to shape”), from fōrma (“shape, form”).^[9][4][8] The Anglo-Norman verb is recorded from the second quarter of the 13th century, meaning to shape, to make like, to adapt and to agree.^[10] The OED notes much confusion between conform and confirm in the 14th to 16th centuries, each often written for the other, which may reflect a dialect pronunciation.^[5]

Earliest recorded meaning

To form or shape according to a pattern; to make like: before 1340, in Richard Rolle's Psalter.^[5] Etymonline gives the mid-14th-century sense "to be obedient (to God), comply",^[3] and the Wycliffite Bible (about 1384) has nyle ȝe be confoormed ... to this world.^[2]

Semantic evolution

The transitive sense "to bring into harmony, adapt" is recorded from 1377, in Langland's Piers Plowman, and the reflexive "to make oneself like" from about 1400.^[5][3] According to Weekley, the modern intransitive sense grew out of the earlier reflexive one;^[11] it is first recorded in 1393, again in Langland.^[5] Chaucer used the verb three times and Gower six, for "conform" and "obey, consent".^[12] From the early 17th century it meant specifically to comply with the usages of the Church of England (1622 in the OED, the 1610s in Etymonline),^[5][3][11] hence conformist in the 1630s, opposed to nonconformist or dissenter.^[3] Johnson (1755) defined the transitive verb as to reduce something to the like appearance, shape or manner of something else.^[13] The use of things, to have the same form or follow a pattern, dates from 1699.^[5]

Usage notes

The adjective conform, similar or consistent (from 1447), comes from French conforme, from Late Latin cōnfōrmis;^[5][8] it is now archaic or rare,^[8][6] but Scottish writers have used conform to as an adverb, "in accordance with", since 1535.^[5][8][15]
