Etymology — The origins of English words

From rhin- + -al.

From ringlet + -ed.

From Latin remanens, present participle of remaneō (“to remain”).

Alteration of propeller.

From Middle French réductif, from Late Latin reductivus, from the participle stem of Latin reducere (“to reduce”).

Borrowed from Latin quadriceps, literally “four-headed”, from quadri- + -ceps, from quattuor (“four”) and from caput (“head”).

From red + bird.

From Middle English provendre, from Old French provendre, variant of provende (“allowance, provision”), from Late Latin praebenda (“a payment, in Medieval Latin also an allowance of food and drink, pittance, also a prebend”). Doublet of prebend.

In use since at least 1856 (Webster's Ninth New Collegiate Dictionary, published 1985). From French récalcitrance.

From Late Latin prothesis, prosthesis, alteration (dropping the ‘s’) from Ancient Greek πρόσθεσις (prósthesis, “addition, augmentation”), (English prosthesis) from προστίθημι (prostíthēmi, “to add”), from πρός (prós, “towards”) + τίθημι (títhēmi, “to place”), from Proto-Indo-European *próti, *préti + *dʰédʰeh₁- (“to be putting, to be placing”). However, often confused for a descendant of the Ancient Greek word πρόθεσις (próthesis, “a preposing, preposition”) (without the σ (s)), which is instead the source of a different term – see alternative etymology, below.

Borrowed from Medieval Latin pūnctuātus, perfect passive participle of pūnctuō (“to mark with points”), from Medieval Latin pūnctus (“a point, dot”), from pungō (“to prick, punch”); see -ate (verb-forming suffix) and -ate (adjective-forming suffix). Doublet of punch.

From Middle English rankenesse, equivalent to rank + -ness.

From Italian rilievo.

Borrowed from Hindi राजबाड़ी (rājbāṛī).

The adjective is derived from Middle English purblind (“(adjective) completely blind; blind in one eye; near-sighted; (noun) near-sighted animal, specifically a hare”) [and other forms], possibly from pur, pure (“completely, entirely”) (ultimately from Proto-Indo-European *pewH- (“to be clean; pure”); influenced by pur- (prefix meaning ‘completely; forward; in advance’)) + blind (“sightless, blind”) (ultimately from Proto-Indo-European *bʰlendʰ- (“to blend, mix up; to make cloudy or opaque”)). Adjective sense 4.1 (“completely blind”) was the original sense. The senses denoting partial blindness are possibly the result of confusion of the first element pur- with poor, perhaps through folk etymology. (Compare parboil regarding per versus pars.) The noun and verb are derived from the adjective.

From record + keeping.

From own, possibly born out of a typographical error (the adjacency of o and p on qwerty keyboards).

From profile + -ist.

From Middle English profoundnesse, equivalent to profound + -ness.

From repose + -ful.

By surface analysis, prosth- + -odont + -ics

From Middle English rier garde, from Anglo-Norman reregard, reregarde, rereguarde and Middle French rieregarde, from Old French rereguarde (attested in The Song of Roland, c. 1150), from rere (“after; behind”) + guarde (“guard”). By surface analysis, rear + guard. Piecewise doublet of retrogarde.

From quadrangulate + -ion.

Blend of re- + decapitate.
