puck

"hockey disk," 1891, possibly from puck (v.) "to hit, strike" (1861), which perhaps is related to poke (q.v.) via notion of "push." Another suggestion traces the noun to Ir. poc "bag." Puckster headlinese for "ice hockey player" is attested from 1939.

Puck

"mischievous fairy" (in "A Midsummer Night's Dream"), probably from pouke "devil, evil spirit" (c.1300), from O.E. puca, cognate with O.N. puki "devil," of unknown origin (cf. pug). Capitalized since 16c. His disguised name was Robin Goodfellow.

pajamas

1800, pai jamahs "loose trousers tied at the waist," worn by Muslims in India and adopted by Europeans there, especially for nightwear, from Hindi pajama, probably from Pers. paejamah, lit. "leg clothing," from pae "leg" (from PIE *ped- "foot," see foot) + jamah "clothing." Modern spelling (U.S.) is from 1845. British spelling tends toward pyjamas.
