wast

n.

'waist'

(Modern English waist)

Etymology

The nearest formal analogues to ME wast (PDE waist) are a group of Gmc nouns formed on the pres. stem of the PGmc v. *waxsan- ‘to grow’ (cp. OE weaxan, etc.) with a -t suffix: masc. u-stems in Go and ON (cp. Go wahstus ‘growth, statute’ and OIcel vǫxtr ‘size, stature; growth (etc.)'); and fem. i-stems in Go uswahsts ‘growth’ and OHG, OS (gi)wahst ‘growth’. There is no direct cognate to these formations attested in OE, which has the very closely related wæstm (masc. or neut.) ‘growth; fruit; product; abundance (etc.)’ (cp. OS wastum), formed from *waxs-t- with an additional -m.  The existence of this word, which shows the same change /xst/ > /st/ which we must assume in ME wast, together with the widespread Gmc cognates persuade most authorities that ME wast represents an OE *wæst, *weaxt. Knigge (79) derives ME wast solely from ON vǫxstr and there is a single occurrence of a n. at a1225 Lamb.Hom.Creed (Lamb 487) 77 (see MED s.v.) with a spelling implying medial /ks/. The sense ‘waist’ is not known for any of the Gmc cognates, but a development from ‘size (of the body)’, i.e. ‘(measurement of) girth’ is wholly plausible.
