erect

Pronunciation

• /ɪˈɹɛkt/^[1]

Etymology

The adjective is borrowed from Latin ērēctus (“upright, raised, lofty”),^{[2][3][4][5][6]} the past participle of ērigō (“to raise, set up”),^[2][3][7][8] formed from ē- (“out, up”), a form of ex- used before r,^[5][4] and regō (“to direct, keep straight, guide”).^[3][7][2][9] Etymonline traces the Latin verb to Proto-Indo-European *reg- (“to move in a straight line”),^[3] and the American Heritage Dictionary refers it to the same root.^[4] Besides "upright", the Latin participle could mean "elevated", "alert, eager", "resolute" and "arrogant".^[3] The verb, erecten,^[10][11] is according to Etymonline either a back-formation from the adjective or taken directly from the Latin participle;^[3] Barnhart thinks both played a part,^[5] while the OED derives it from the Latin participial stem ērēct-.^[2] The word belongs to the same Latin family as regent, region and direct,^[7][6] and Barnhart refers the root to right.^[5]

Earliest recorded meaning

Upright, not bending forward or down: about 1386, in Chaucer's Man of Law's Tale,^[2][5] where a tree's shadow is compared with the length of a body standing erect.^[10] Hoad notes that the adjective is rare before the 16th century.^[12]

Semantic evolution

The verb first meant to direct upwards or to set upright,^[5][10] and soon also to set up or build (1417, in Barnhart).^[5] From the 15th to the 18th century it was also used for raising someone to a dignity or office and for lifting up the eyes or hands, while rousing the mind is a 16th- to 18th-century use; the Shorter Oxford marks these senses obsolete.^[8][2] The adjective likewise had a figurative sense, of a mind lifted up and alert (1544–1757), and was used of an unabashed face (1618–1796).^[2] Johnson (1755) defined it as "upright; not leaning; not prone".^[13] The building sense spread to founding institutions, raising an army, drawing a perpendicular in geometry and casting a horoscope in astrology.^[8] Specialised uses followed in botany and heraldry (1688),^[2] in optics, of an image that is not inverted (1855),^[2][8] and in physiology: from 1626, in Bacon, the verb was used of setting up a part of the body or pricking up the ears, and later of making an organ rigid,^[2] and the adjective is recorded of the penis, nipples or clitoris from 1897.^[2]
