prostitute (v.)

1520s, "to offer to indiscriminate sexual intercourse" (usually in exchange for money), from Latin prostitutus, past participle of prostituere, etymologically "place before or in front," hence "expose publicly," and especially "expose to prostitution."

It was somewhat earlier used in English as an adjective, "offered or exposed to lust" (1570s), earlier still in the figurative sense of "debased, devoted to vile or infamous purposes" (1560s).

The notion of "sex for hire" is not inherent in the etymology, which rather suggests one "exposed to lust" (by herself or another) or sex "indiscriminately offered."

Protest vote, "vote cast to demonstrate dissatisfaction with the choice of candidates or the current system," is by 1905 (in reference to Socialist Party candidates).

protest (v.)

mid-15c., protesten, "to declare or state formally or solemnly, bear witness or testimony to," from Old French protester and directly from Latin protestari "declare publicly, testify, protest" (see protest (n.)). Original sense preserved in to protest one's innocence. The meaning "make a solemn or formal declaration (often in writing) in condemnation of an act or measure, proposed or accomplished," is from c. 1600. The word's association with marches and rallies arose in 20c. Related: Protested; protesting.

Protestantism (n.)

"state of being a Protestant; religious principles of Protestants," 1640s, from French protestantisme or else formed from Protestant + -ism. Meaning "Protestant Christians or churches" is from 1660s.

Proteus

c. 1400, Protheus, from Old French, ultimately from Greek Proteus, the name of the mythological sea-god who had the power of assuming different shapes at will (see Protean).

prothalamion (n.)

"song sung before a wedding, piece written to celebrate a marriage," 1590s, coined as a poem title ("Prothalamion, or a Spousall Verse") by Edmund Spenser (based on epithalamion) from Greek pro "before" (see pro-) + thalamos "bridal chamber" (see thalamus). Sometimes Latinized as prothalamium.

prothesis (n.)

a Greek word used in various senses in English; from Greek prothesis "a putting, a placing before, a placing in public," from pro "before" (see pro-) + thesis "a placing" (from reduplicated form of PIE root *dhe- "to set, put"). In the ecclesiastical sense ("preparation of the eucharistic elements before the liturgy in the Greek Church") from 1670s; grammatical sense ("addition of one or more sounds or letters at the beginning of a word") is by 1870. Related: Prothetic (1835 in grammar); prothetical; prothetically.

prothonotary (n.)

also protonotary (under which spelling it appears in OED print edition), mid-15c., "principal clerk of a court," from Medieval Latin prothonotarius, from a Late Latin borrowing of Greek prōtonotarios "first scribe," originally the recorder of the court of the Byzantine empire, from prōtos "first" (see proto-) + Latin notarius (see notary). Related: Prothonotarial.

The -h- appeared in Medieval Latin, perhaps because Greek prōto- sometimes became prōth- (before an aspirated vowel); it was carried into Old French, which passed it to Middle English. Other Middle English proto- words from French also had variants in protho- (prothomartir "earliest martyr," Protheus "the god Proteus," prothogol "protocol," all 15c.), but soon it was purged from the others; prothonotary kept its perhaps through the powerful and necessary conservatism of legal language.

protist (adj.)

"of or pertaining to the Protista," one of the biological kingdoms proposed by Haeckel, including the Protozoa and Protophyta, the simplest animals and plants, 1869, from Modern Latin Protista (German Protisten, Haeckel, 1868), from Greek neuter plural of prōtistos "the very first," superlative of prōtos "first" (see proto-).

proto-

before vowels prot-, word-forming element in compounds of Greek origin meaning "first, source, parent, preceding, earliest form, original, basic," from Greek prōto-, from prōtos "first" (from PIE *pre-, from root *per- (1) "forward," hence "before, first"). It is also used in forming words in the sciences and to form compounds having historical reference (such as Proto-Indo-European).

protocol (n.)

mid-15c., prothogol, "prologue;" 1540s, prothogall, "draft of a document, minutes of a transaction or negotiation, original of any writing" (senses now obsolete), from French prothocole (c. 1200, Modern French protocole), from Medieval Latin protocollum "draft," literally "the first sheet of a volume" (on which contents and errata were written), from Greek prōtokollon "first sheet glued onto a manuscript," from prōtos "first" (see proto-) + kolla "glue," a word of uncertain origin.

The sense developed in Medieval Latin and French from "rough draft; original copy of a treaty, etc." to "official record of a transaction," to "diplomatic document" (especially one signed by friendly powers to secure certain ends by peaceful means), and finally, in French, to "formula of diplomatic etiquette." That final sense is attested in English by 1896.

The general sense of "conventional proper conduct" is recorded from 1952. "Protocols of the (Learned) Elders of Zion," Russian anti-Semitic forgery purporting to reveal Jewish plan for world domination, first was published in English 1920 under title "The Jewish Peril."

Proto-Indo-European (n.)

proto-language (n.)

"a hypothetical extinct parent language from which existing languages have descended," 1948, from proto- + language.

proton (n.)

1920 in physics sense of "sub-atomic particle with a positive charge," coined by British physicist Ernest Rutherford (1871-1937) from noun use of Greek prōton, neuter of prōtos "first" (see proto-), on analogy of electron; supposedly because hydrogen (the nucleus of which, in its commonest form, consists of one proton) was hypothesized as a constituent of all the elements. The word was used earlier in embryology (1893) as a translation of German anlage ("fundamental thing") based on Aristotle's phrase he prote ousia to proton.

protoplanet (n.)

"large, diffuse cloud of matter in the orbit of a young star, regarded as the preliminary state of a planet," 1949, from proto- + planet.

protoplasm (n.)

"substance forming the essential stuff of the cells of plants and animals," 1848, from German Protoplasma (1846), used by German botanist Hugo von Mohl (1805-1872), on notion of "first-formed," from Greek prōtos "first" (see proto-) + plasma "something formed or molded" (see plasma).

The word was in Medieval Latin with a sense of "first created thing," and it might have existed in ecclesiastical Greek in a different sense. It was used 1839 by Czech physiologist Johannes Evangelista Purkinje (1787-1869) to denote the gelatinous fluid found in living tissue. The modern meaning is a refinement of this. This word prevailed, though German language purists preferred Urschleim. Related: Protoplasmal; protoplasmic.

In English from 1590s as prototypon.

protozoic (adj.)

1838, in geology, in reference to rocks containing fossils of the earliest life on Earth, from proto- "early, first" + Greek zoe "life" (from PIE root *gwei- "to live") + -ic. Coined by British geologist Adam Sedgwick, who wrote in 1852, "I used the word Protozoic to prevent any wrangling about the words Cambrian and Silurian" [Quarterly Journal of the Geological Society of London].

In zoology by 1861, "of or pertaining to the Protozoa," from Protozoa + -ic. Alternative adjectives in the biological sense include Protozoan, Protozoal.

Protozoa (n.)

"primordial or first-formed animals, cell-animals," 1828, from Modern Latin Protozoa, coined 1818 by German zoologist Georg August Goldfuss (1782-1848) from Greek prōtos "first" (see proto-) + zoia, plural of zoion "animal" (from PIE root *gwei- "to live"). Originally including sponges and corals; current sense is from 1845. Related: Protozoon (singular), also Protozoön; Protozoan.

The English verb survived chiefly in the past-participle adjective.

The phrase is attested by 1832.

protractor (n.)

1610s, "one who lengthens (an action)," Modern Latin agent noun from Latin protrahere "to draw forward" (see protraction). Medieval Latin protractor meant "one who calls or drags another into court."

protrude (v.)

1610s, "to thrust forward or onward, to drive along;" 1640s, "to cause to stick out," from Latin protrudere "thrust forward; push out," from pro "forward" (see pro-) + trudere "to thrust, push" (from PIE *treud- "to press, push, squeeze;" see threat).
