linnet (n.) Look up linnet at Dictionary.com
small finch-like songbird, 1530s, from Middle French linette "grain of flax," diminutive of lin "flax," from Latin linum "linen" (see linen). Flaxseed forms much of the bird's diet. Old English name for the bird was linetwige, with second element perhaps meaning "pluck." This yielded Middle English and dialectal lintwhite.
