ado

ado: [14] In origin, ado (like affair) means literally ‘to do’. This use of the preposition at (ado = at do) is a direct borrowing from Old Norse, where it was used before the infinitive of verbs, where English would use to. Ado persisted in this literal sense in northern English dialects, where Old Norse influence was strong, well into the 19th century, but by the late 16th century it was already a noun with the connotations of ‘activity’ or ‘fuss’ which have preserved it (alongside the indigenous to-do) in modern English.

ado (n.)

late 14c., "conflict, fighting; difficulty, trouble," compounded from at do, dialectal in Norse influenced areas of England for to do, as some Scandinavian languages used at with infinitive of a verb where Modern English uses to. For sense development, compare to-do. Meaning "fuss" is from early 15c. Also used in Middle English for "dealings, traffic," and "sexual intercourse" (both c. 1400).
