elk (n.)youdaoicibaDictYouDict
late Old English elch, from Old Norse elgr or from an alteration of Old English elh, eolh (perhaps via French scribes), or possibly from Middle High German elch (OED's suggestion), all from Proto-Germanic *elkh- (source also of Old High German elaho). The modern word "is not the normal phonetic representative" of the Old English one [OED].

The Germanic words are related to the general word for "deer" in Balto-Slavic (such as Russian losu, Czech los; also see eland), from PIE *olki-, perhaps with reference to the reddish color from root *el- (2) "red, brown" (in animal and tree names); compare Sanskrit harina- "deer," from hari- "reddish-brown." Greek alke and Latin alces probably are Germanic loan-words. Applied to similar-looking but unrelated animals in North America. Benevolent and Protective Order of Elks founded N.Y.C. 1868, originally a society of actors and writers.
ell (n.1)youdaoicibaDictYouDict
unit of measure, Old English eln, originally "forearm, length of the arm" (as a measure, anywhere from a foot and a half to two feet), from PIE *el- (1) "elbow, forearm" (cognates: Greek olene "elbow," Latin ulna, Armenian uln "shoulder," Sanskrit anih "part of the leg above the knee," Lithuanian alkune "elbow").

The exact distance varied, in part depending on whose arm was used as the base and whether it was measured from the shoulder to the fingertip or the wrist: the Scottish ell was 37.2 inches, the Flemish 27 inches. Latin ulna also was a unit of linear measure, and compare cubit. The modern English unit of 45 inches seems to have been set in Tudor times.
Whereas shee tooke an inche of liberty before, tooke an ell afterwardes [Humfrey Gifford, "A Posie of Gilloflowers," 1580].
