þeód-wrecanto avenge thoroughly, take great vengeance for :-- Grendles módor gegán wolde sorhfulue síð, sunu þeódwrecan (Ettmüller would read suna deáð wrecan; but perhaps the force of þeód- here and its composition with a verb may be illustrated by the case of full-, which is compounded with verbs, and has the force of per-; see the verbs in the Dictionary. The parallel between full- and þeód- might be further illustrated from compound adjectives in Icelandic, e.g. full-glaðr and þjóð-glaðr, full-góðr and þjóð-góðr), Beo. Th. 2561; B. 1278.
