[OE. swíðe = OS. swîðo (MLG. swide, swît), OFris. swîthe, swîde, OHG., MHG. swinde (later swint, schwind(t), mod.G. geschwind, dial. schwind-e), adv. of Com. Teut. adj. represented by OE. swíþ strong (surviving in ME. only in the compar. SWITHER) = OS. swîði, swîð strong, powerful, sudden (MLG. swîde, swît), OHG., MHG. swinde strong, rapid (as the second element in many personal names, as Wolfswind, Amalswind), early mod.G. schwind-e, ON. svinnr swift, quick, wise, Goth. swinþs strong; of doubtful origin.
The normal modern representative of OE. swíðe would have been (swəið). The reduction of ME. swīthē to one syllable (swīð) took place first in the north (Cursor Mundi). Evidence of normal shortening of the stem-vowel in the compar. swyþþer appears late in the 14th cent.; there is no clear evidence of shortening in the positive till late in the 16th cent.]
