Origin of flatter

From flat + -er (comparative suffix). Compare Icelandic flatari (“flatter, more flat”).

*From Middle English flatteren, flateren (“to flutter, float, fawn over”), probably a conflation of Old English floterian, flotorian (“to flutter, float, be disquieted”), from Proto-West Germanic *flotrōn, from Proto-Germanic *flutrōną (“to be floating”), from Proto-Indo-European *plewd- (“to flow, swim”), equivalent to float + -er; and Old Norse flaðra (“to fawn on someone, flatter”), from Proto-Germanic *flaþrōną (“to fawn over, flutter”), from Proto-Indo-European *peled- (“moisture, wetness”), *pel- (“to gush, pour out, fill, flow, swim, fly”). Cognate with Scots flatter, flotter (“to float; splash; cover with liquid”), Middle Dutch flatteren (“to embellish, flatter, caress”), German flattern (“to flutter”). *The word was also falsely associated with Middle French flatter (“to flatter, to caress with the flat of the hand”), from Old French flater (“to deceive by concealing the truth, to stroke with the palm of the hand”), from Frankish *flat (“palm, flat of the hand”), from Proto-Germanic *flatą, *flatō (“palm, sole”), from *flataz (“flat”), probably from Proto-Indo-European *pleth₂-, *pleh₂- (“flat, broad, plain”); related to Old High German flazza (“palm, flat of the hand”)...

From flat (“to make flat, flatten”) + -er (agent suffix).
