c. 1400, pallour, "paleness, dullness," from Old French palor "paleness, whiteness" (12c.) and directly from Latin pallor, from pallere "be pale, turn pale," related to pallus "dark-colored, dusky," from PIE root *pel- (1) "pale."
[P]aleness in the Mediterranean is not so much the lack of color as a sickly, yellowish, sallow complexion, compared here to the hue of a gilded bronze statue. Sappho compared it to the color of dead grass. [Daniel H. Garrison, note on pallidor in poem 81 in "The Student's Catullus, 2nd ed., 1995]
"impose (something) on (someone) by fraud," 1670s, from palm (n.1); around the same time it also meant "conceal in the palm of the hand" (1670s) and "handle, manipulate" (1680s). Extended form palm off (something, on someone) is from 1822.
tropical tree of the order Palmae; the date-palm, Middle English palme, from Old English palma, Old French palme, both from Latin palma "palm tree," originally "palm of the hand;" the tree so called from the shape of its leaves, like fingers of a hand (see palm (n.1)).
The word traveled early to northern Europe, where the tree does not grow, via Christianity, and took root in the local languages (such as Old Saxon palma, Old High German palma, Old Norse palmr); Palm Sunday, the Sunday before Easter, commemorating Christ's triumphal entry into Jerusalem, is Old English palm-sunnandæg. In ancient times, a leaf or frond of the palm was carried or worn as a symbol of victory or triumph, or on feast days; hence figurative use of palm for "victory, triumph" (late 14c.).
Palm Beach, Florida, named for the palm groves there, was established as a luxury resort c. 1900 by railroad magnate Henry Flagler. Palm court "large room in a hotel, etc., usually decorated with potted palms" is recorded by 1908.
"flat of the hand, inner surface of the hand between the wrist and the fingers," c. 1300, paume, from Old French paume, palme (Modern French paume), from Latin palma "palm of the hand," also "flat end of an oar; palm tree," from PIE root *pele- (2) "flat; to spread" (source also of Greek palamē "open hand," Old Irish lam, Welsh llaw, Old English folm, Old High German folma "hand," Sanskrit panih "hand, hoof").
Palm oil is earlier in the punning sense of "bribe" (1620s) than in the literal sense of "fatty oil obtained from the fruit of the West African palm" (1705, from palm (n.2)).
"pilgrim; itinerant monk going from shrine to shrine under a perpetual vow of poverty;" originally "pilgrim who has returned from the Holy Land," c. 1300, palmere (mid-12c. as a surname), from Anglo-French palmer (Old French palmier), from Medieval Latin palmarius, from Latin palma "palm tree" (see palm (n.2)). So called because they wore palm branches in commemoration of the journey. "The distinction between pilgrim and palmer seems never to have been closely observed" [Century Dictionary].
type of fan-leaf palm, 1580s, from Spanish palmito "dwarf fan palm tree," diminutive of palma "palm tree," from Latin palma (see palm (n.2)). The suffix was subsequently Italianized.

"art or practice of divination from the palm of the hand," especially by its lines, mid-15c., paumestri, from palme (see palm (n.1)) + obscure second element, perhaps -estre (as in Middle English webbestre "weaver") or -rie (as in Middle English archerie "archery"). Palmist (n.) is an 1886 back-formation; the earlier agent noun was palmister (c. 1500)..
