swank (adj.)
"stylish, classy, posh," 1913, from earlier noun or verb; "A midland and s.w. dial. word taken into general slang use at the beginning of the 20th cent." [OED]; compare swank (n.) "ostentatious behavior," noted in 1854 as a Northampton word; swank (v.), from 1809 as "to strut, behave ostentatiously." Perhaps ultimately from Proto-Germanic *swank-, from PIE *sweng(w)-, a Germanic root meaning "to swing, turn, toss" (source also of Middle High German swanken "to sway, totter, turn, swing," Old High German swingan "to swing;" see swing (v.)). Perhaps the notion is of "swinging" the body ostentatiously (compare swagger).

A separate word-thread derives from Old English swancor "pliant, bending," and from this comes swanky (n.) "active or clever young fellow" (c. 1500).
sway (v.)
early 14c., "move, go, go quickly; move (something) along, carry," probably from a Scandinavian source akin to Old Norse sveigja "to bend, swing, give way," Old Danish svegja, perhaps merged with an unrecorded Old English cognate. The whole group might be related to swag (v.) and swing (v.).

The sense of "swing, waver, move in a swaying or sweeping motion" is from late 14c. Meaning "move from side to side" is from c. 1500; transitive sense "cause to move from side to side" is from 1550s (according to OED, not common before 19c.).

Or perhaps directly from the Old English word, with narrowing of sense.
