From Middle English streight, streght, streiȝt, the past participle of strecchen (“to stretch”), from Old English streċċan (past participle ġestreaht, ġestreht), from Proto-West Germanic *strakkjan (“to stretch”). Cognate with Scots straicht (“straight”), Dutch gestrekt (“stretched”), German gestreckt (“stretched”), Danish strakt (“stretched”), Faroese and Norn strekti (“stretched”), Icelandic strekkti (“stretched”), Norwegian strekte (“stretched”), Swedish sträckte (“stretched”). Doublet of straught. Equivalent to stretch + -ed. In some senses, conflated with strait (“narrow, constricted”), which is from Latin strictus via Old French estreit.
