- brook (n.)
- "small stream," Old English broc "flowing stream, torrest," of obscure origin, probably from Proto-Germanic *broka- which yielded words in German (Bruch) and Dutch (broek) that have a sense of "marsh." In Sussex and Kent, it means "water-meadow," and in plural, "low, marshy ground."
- brook (v.)
- "to endure," Old English brucan "use, enjoy, possess; eat; cohabit with," from Proto-Germanic *bruk- "to make use of, enjoy" (source also of Old Saxon brukan, Old Frisian bruka, Old High German bruhhan, German brauchen "to use," Gothic brukjan), from PIE root *bhrug- "to make use of, have enjoyment of" (source also of Latin fructus). Sense of "use" applied to food led to "be able to digest," and by 16c. to "tolerate."
