Origin & History of “run”

Run is quite a widespread Germanic verb, represented also by German rennen and Swedish ränna. Its ultimate ancestry is not known, although links have been suggested with Sanskrit rnoti ‘he moves’ and Greek órnūmi ‘rouse’. The Old English verb was rinnan; run, which was originally a past form, did not begin to emerge as the infinitive until the early 14th century, and it was not common until the 16th century. Runnel ‘brook’ (OE) comes from the same Germanic source, and rennet may be related.
