kind of round hat, c. 1500, from French toque (15c.), from Spanish toca "woman's headdress," possibly from Arabic *taqa, from Old Persian taq "veil, shawl."
also chako, cylindrical soldier's headdress with plume or pompon, 1815, from Hungarian csákó, short for csákós süveg "peaked cap," from adjectival form of csákó "peak, projecting point of a cow's horn," which some European etymologists derive from German zacken "point, spike," but which Hungarian sources regard as of unknown origin. Worn by infantry soldiers in 18c.-19c.
also gymp, ornamental material for trimming dresses, furniture, etc., 1660s, probably from French guimpe, Old French guimple "wimple, headdress, veil" (12c.), from Frankish *wimpil- or some other Germanic source (compare Old High German wimpal, and see wimple).
1550s, "headdress of the Persian kings" (also worn by men of rank), from Latin tiara, from Greek tiara, of unknown origin. Earlier in Englished form tiar (1510s). As a richly jeweled headband in Western wear, 1650s (tiar; 1718 as tiara). Related: Tiaraed.
1560s, from French turbant (15c.), from Italian turbante (Old Italian tolipante), from Turkish tülbent "gauze, muslin, tulle," from Persian dulband "turban." The change of -l- to -r- may have taken place in Portuguese India and thence been picked up in other European languages. A men's headdress in Muslim lands, it was popular in Europe and America c. 1776-1800 as a ladies' fashion. Related: Turbaned.
mausoleum at Agra, India, built by Shah Jahan for his favorite wife, from Persian, perhaps "the best of buildings," with second element, mahal, from Urdu mahall "private apartments; summer house or palace," from Arabic halla "to lodge." But some authorities hold that the name of the mausoleum is a corruption of the name of the woman interred in it, Mumtaz (in Persian, literally "chosen one") Mahal, who died in 1631. Persian taj is literally "crown, diadem, ornamental headdress," but here denoting an object of distinguished excellence. Figurative use of Taj Mahal in English as a name denoting anything surpassing or excellent is attested from 1895.
early 15c., "kind of cap or bonnet worn by men and women," from Old French bonet, short for chapel de bonet, a cap made from bonet "kind of cloth used as a headdress" (12c., Modern French bonnet), from Medieval Latin bonitum, bonetum "material for hats," which is perhaps a shortening of Late Latin abonnis "a kind of cap" (7c.), which is perhaps from a Germanic source. (If that is correct, a chapel de bonet would be etymologically a "cap made of cap").
As a form of head-covering worn by women out-of-doors, bonnet is attested from late 15c. As a type of mechanical covering device, by 1862.
1786, "decorative chest of drawers for holding clothes, handy articles, etc.," earlier (1680s) name of a type of fashionable ladies' large, high headdress mounted on a wire frame, from French commode, noun use of adjective meaning "convenient, suitable," from Latin commodus "proper, fit, appropriate, convenient, satisfactory," from com-, here perhaps an intensive prefix (see com-), + modus "measure, manner" (from PIE root *med- "take appropriate measures"). Meaning "chair housing a chamber pot," usually kept in a bedroom, is first attested 1851 from notion of "convenience."
I wash'd and patch'd, to make me look provoking,
Snares that they told me wou'd catch the men;
And on my head a huge commode sat cocking,
Which made me shew as Tall agen:
[from a song in "Wit and Mirth," 1719]
early 14c., "close-fitting cap worn by women," from French cale "cap," back-formation from calotte, from Italian callotta, from Latin calautica "type of female headdress with pendent lappets," a foreign word of unknown origin.
The "cap" sense was the main one until 17c. Medical use, in reference to various membranes, dates to late 14c.; especially of the amnion enclosing the fetus before birth from 1540s. This, if a child was born draped in it, was supersititously supposed to betoken prosperity, give the gift of eloquence, and protect against drowning (18c. seamen paid dearly for one, and cauls were advertised for sale in British newspapers through World War I).
