1 ÞIND
f., not þynd, as it is sometimes spelt by modern writers, the i is determined by the old rhyme vindr í sal þindar, Edda l. c.; [from þenja, prop. what is stretched out; Lat. tent-orium, although different in sense, seems really to be the same word]:—the diaphragm; the word is very freq. in mod. usage, although not recorded in old writers except in this sole instance; salr þindar, the breast, Edda ii. 363 (in a verse), þindar-lauss, adj. without a diaphragm, one who is never out of breath in running, esp. used as an epithet of the fox.
