- suds (n.)
- 1540s, "dregs, leavings, muck," especially in East Anglia, "ooze left by flood" (this may be the original sense), perhaps borrowed from Middle Dutch sudse "marsh, bog," cognate with Old English soden, past participle of seoþan (see seethe). Meaning "soapy water" dates from 1580s; slang meaning "beer" first attested 1904.
