mid-14c., "one who consoles or supports in distress, anger, etc." (originally in religious use, with capital C-, "the Holy Ghost"), from Anglo-French confortour (Old French conforteor) "helper, adviser, supporter," from Vulgar Latin *confortatorem, agent noun from Late Latin confortare "to strengthen much" (see comfort (v.)). As a kind of knitted, crocheted scarf fit for tying around the neck in cold weather, from 1817; as a kind of quilted coverlet, from 1832.
the hand opposed to the left hand, late Old English rihthand; see right (adj.2) + hand (n.). So called as the one normally the stronger of the two. Applied to the right side generally by c. 1200. As a symbol of friendship or alliance, by 1590s. Figurative for "indispensable helper, person of use or importance," 1520s (right-hand man is attested by 1660s). Right-handed "having the right hand more useful than the left" is attested from late 14c.; as an adjective from c. 1700. Right-hander, of persons, "one who uses the right hand more skillfully than the left" is by 1885.
mid-15c., Paraclit, a title of the Holy Spirit, from Old French paraclet (13c.), from Medieval Latin paracletus, from a Church Latin rendering of Greek paraklētos "advocate, intercessor, legal assistant," noun use of an adjective meaning "called to one's aid," from parakalein "to call to one's aid," in later use "to comfort, to console," from para (see para- (1)) + kalein "to call" (from PIE root *kele- (2) "to shout").
[I]n the widest sense, a helper, succorer, aider, assistant; so of the Holy Spirit destined to take the place of Christ with the apostles (after his ascension to the Father), to lead them to a deeper knowledge of gospel truth, and to give them the divine strength needed to enable them to undergo trials and persecutions on behalf of the divine kingdom .... [Thayer, "A Greek-English Lexicon of the New Testament," 1889]
But also sometimes translated in English bibles as Advocate, on the notion of "intercession." The word was earlier borrowed directly from Latin as paraclitus (early 13c.).
Old English help (m.), helpe (f.) "assistance, succor," from Proto-Germanic *helpo (source also of Old Norse hjalp, Swedish hjälp, Old Frisian helpe, Dutch hulp, Old High German helfa, German Hilfe), from the source of help (v.).
The use of help as euphemism for "servant" is American English, 1640s (originally in New England). Bartlett (1848) describes it as "The common name in New England for servants, and for the operatives in a cotton or woollen factory." Most early 19c. English writers travelling in America seem to have taken a turn at explaining this to the home folks.
A domestic servant of American birth, and without negro blood in his or her veins ... is not a servant, but a 'help.' 'Help wanted,' is the common heading of advertisements in the North, when servants are required. [Chas. Mackay, "Life and Liberty in America," 1859].
But help also meant "assistant, helper, supporter" in Middle English (c. 1200).
also help-meet, a ghost word from the 1611 "King James" translation of the Bible, in which it was at first a two-word noun-adjective phrase translating Latin adjutorium simile sibi [Genesis ii.18] as "an help meet for him," and meaning literally "a helper like himself."
Robert Alter ("The Five Books of Moses," 2004) suggests sustainer beside him as the closest possible in English to the original:
The Hebrew 'ezer kenegdo (King James Version "help meet") is notoriously difficult to translate. The second term means "alongside him," "opposite him," "a counterpart to him." "Help" is too weak because it suggests a mere auxiliary function, whereas 'ezer elsewhere connotes active intervention on behalf of someone, especially in military contexts, as often in Psalms. ["Five Books of Moses," footnote to Gen. ii.18].
"one who provides others with the means and opportunity of gratifying their sexual lusts," c. 1600, of unknown origin, perhaps from French pimpant "alluring in dress, seductive," present participle of pimper "to dress elegantly" (16c.), from Old French pimpelorer, pipelorer "decorate, color, beautify." Weekley suggests French pimpreneau, defined in Cotgrave [French-English Dictionary, 1611] as "a knave, rascall, varlet, scoundrell," but Liberman is against this.
Judging by such recorded meanings of pimp as 'helper in mines; servant in logging camps,' this word was originally applied to boys and servants. [Liberman]
The word also means "informer, stool pigeon" in Australia and New Zealand and in South Africa, where by early 1960s it existed in Swahili form impimpsi. Pimpmobile first recorded 1973 (six years before Popemobile).
PIMP. A male procurer, or cock bawd; also a small faggot used about London for lighting fires, named from introducing the fire to the coals. [Grose, "Dictionary of the Vulgar Tongue," London, 1785]
Among the lists of late Middle English terms for animal groupings was a pimpe of chickens (or birds), mid-15c., a variant of pipe "flock" (mid-14c.), from Old French pipee.
