Word History
Etymology
Adjective
Middle English red, rede, reed, going back to Old English rēad, going back to Germanic *rauđa- (whence also Old Frisian rād, rōd "red, yellow," Old Saxon rōd "red," Middle Dutch root, rood, Old High German rōt, Old Norse rauðr, Gothic rauþs), going back to Indo-European *h1rou̯dh-o-, whence also Old Irish rúad "reddish brown, dark red," Welsh rhudd "red, tawny," Latin rūfus (from a dialect or another Italic language, with -f- for expected -b-), Lithuanian raũdas "red-brown, reddish," Russian dialect rúdyj "blood-red," Bosnian-Croatian-Serbian rûd "reddish brown"; from a suffixed zero-grade form *h1rudh-ro-, Old Norse roðra "blood," Latin ruber "red," Tocharian B ratre, Greek erythrós, Sanskrit rudhiráḥ "red, bloody"
Note: The Modern English form reflects shortening of Middle English ę̄ (long open e), found in other monosyllabic words ending in a voiced dental stop (compare dead entry 1, head entry 1, shred entry 1); as with shred, this change took place early enough to be reflected in early Modern English spelling (unlike dead and head). The surnames Read, Reade, etc., may preserve the long vowel.
