Share:
tr.v. redd·ed also redd, redd·ing, redds
Chiefly Pennsylvania
To clear: redd the dinner table.
Phrasal Verb:
redd up
To tidy: redded up the front room.

[Middle English dialectal redden, variant (probably influenced by Middle English redden, to free (from an encumbrance), rescue) of Middle English riddan, to clear (an area, a way), clear out; see RID.]

Our Living Language The terms redd and redd up came to the American Midlands from the many Scottish immigrants who settled there. In the meaning "to clear an area or to make it tidy," redd is still used in Scotland and Northern Ireland. In the United States, the word is especially common in Pennsylvania as part of the phrasal verb redd up.
