early 14c., "small pool of dirty water," frequentative or diminutive of Old English pudd "ditch," related to German pudeln "to splash in water" (compare poodle). Originally used of pools and ponds as well. Puddle-duck for the common domestic duck is by 1846.
1911, from German Gen, coined 1905 by Danish scientist Wilhelm Ludvig Johannsen (1857-1927), from Greek genea "generation, race" (from PIE root *gene- "give birth, beget"). De Vries had earlier called them pangenes. Gene pool is attested from 1946.
method of painting, 1868, from French gouache "watercolors, water-color painting" (18c.), from Italian guazzo "watercolor," originally "spray, splash, puddle, pool," from Latin aquatio "watering, watering place," from aquatus, past participle of aquari "to bring water for drinking," from aqua "water" (from PIE root *akwa- "water").
The elements of the word are Greek, but there is no record of arkhipelagos in ancient or Medieval Greek (the modern word in Greek is borrowed from Italian), so the word perhaps is an Italian compound or an alteration in Italian of Medieval Latin Egeopelagus, from Greek Aigaion pelagos "Aegean Sea." The Aegean being full of island chains, the meaning was extended in Italian to "any sea studded with islands" (a sense attested in English from c. 1600) and to the islands themselves. Related: Archipelagian; archipelagic.
"of or pertaining to a marsh or marshes," 1803, with -al (1) + stem of Latin palus "a swamp, a fen, a marsh," from PIE *pelkiz- (source also of Sanskrit palvala- "pond, pool;" Old Prussian pelky "marsh," Lithuanian pėlkė "marsh," Latvian pelce "puddle"). Alternative formations paludine (1832, from French) and paludinous (1866) are later in English.

early 15c., rakken, "to stretch, stretch out (cloth) for drying," also, of persons, "to torture by violently stretching on the rack," from rack (n.1) or from Middle Dutch or Middle Low German recken. Of other pains from 1580s.
Figurative sense of "subject to strenuous effort" (of the brain, memory, etc.) is by 1580s; that of "to torment, afflict with great pain or distress" is from c. 1600. Meaning "fit with racks" is from 1580s.
Sense of "to place (pool balls, etc.) in a rack" as before starting a game is by 1909 (the noun in this sense is by 1907). Teenager slang meaning "to sleep" is from 1960s (rack (n.) was Navy slang for "bed" in 1940s). Related: Racked; racking. Rack up "register, accumulate, achieve" is attested by 1943 (in Billboard magazine), probably from pool halls, perhaps from a method of keeping score. To rack up formerly was "fill a stable rack with hay or straw for horses kept overnight" (1743).
early 14c., "natural or artificial reservoir for water, bathing pool," from Old French piscine "fishpond," from Latin piscina, from piscis "a fish" (from PIE root *pisk- "a fish"). The ecclesiastical sense (also piscina) "stone basin in a church placed close to the altar and used to receive the water in which the priest washed his hands before the celebration of the eucharist" is from late 15c., from Medieval Latin piscina. As an adjective from 1799.
