pelican (n.)youdaoicibaDictYouDict[pelican 词源字典]
Old English pellicane, from Late Latin pelecanus, from Greek pelekan "pelican" (so used by Aristotle), apparently related to pelekas "woodpecker" and pelekys "ax," perhaps so called from the shape of the bird's bill. Spelling influenced in Middle English by Old French pelican. Used in Septuagint to translate Hebrew qaath. The fancy that it feeds its young on its own blood is an Egyptian tradition properly belonging to some other bird. Louisiana has been known as the Pelican state at least since 1859.[pelican etymology, pelican origin, 英语词源]

pellet (n.)youdaoicibaDictYouDict
mid-14c., from Old French pelote "small ball" (11c.), from Vulgar Latin *pilotta, diminutive of Latin pila "ball, playing ball, the game of ball," perhaps originally "ball of hair," from pilus "hair" (see pile (n.3)).

peninsula of southern Greece, late 15c., from Latin, from Greek Peloponnesos, second element apparently nesos "island" (see Chersonese); first element said to be named for Pelops, son of Tantalus, who killed him and served him to the gods as food (they later restored him to life). The proper name is probably from pellos "dark" + ops "face, eye." But the association with the peninsula name likely is folk etymology. Related: Peloponnesian.

"to strike" (with something), c. 1500, of unknown origin; perhaps from early 13c. pelten "to strike," variant of pilten "to thrust, strike," from an unrecorded Old English *pyltan, from Medieval Latin *pultiare, from Latin pultare "to beat, knock, strike." Or from Old French peloter "to strike with a ball," from pelote "ball" (see pellet (n.)) [Klein]. Watkins says the source is Latin pellere "to push, drive, strike." Related: Pelted; pelting.

"skin of a fur-bearing animal," early 15c., of uncertain origin, perhaps a contraction of pelet (late 13c. in Anglo-Latin), from Old French pelete "fine skin, membrane," diminutive of pel "skin," from Latin pellis "skin, hide" (see film (n.)).

pen (n.3)youdaoicibaDictYouDict
slang, "prison," 1884, shortening of penitentiary; earlier use (1845) probably is a figurative extension of pen (n.2).
pen (n.1)youdaoicibaDictYouDict
"writing implement," late 13c., from Old French pene "quill pen; feather" (12c.) and directly from Latin penna "a feather, plume," in plural "a wing," in Late Latin, "a pen for writing," from Old Latin petna, pesna, from PIE *pet-na-, suffixed form of root *pet- "to rush; to fly" (see petition (n.)).

Latin penna and pinna "a feather, plume;" in plural "a wing;" also "a pinnacle; battlement" (see pin (n.)) are treated as identical in Watkins, etc., but regarded as separate (but confused) Latin words by Tucker and others, who derive pinna from PIE *spei- "sharp point" (see spike (n.1)) and see the "feather/wing" sense as secondary.

In later French, this word means only "long feather of a bird," while the equivalent of English plume is used for "writing implement," the senses of the two words thus are reversed from the situation in English. Pen-and-ink (adj.) is attested from 1670s. Pen name is recorded from mid-19c.
