stir: [OE] The etymological connotations of stir are of ‘agitation’ and ‘disturbance’; the notion of ‘mixing a liquid with circular movements of a spoon or other implement’ is a secondary development. The verb goes back to a prehistoric Germanic *sturjan, whose only other living descendant is Norwegian styrja ‘make a disturbance’. It was formed from a base *stur-, which was probably also responsible for English storm.

stir (v.)youdaoicibaDictYouDict
Old English styrian "to stir, move; rouse, agitate, incite, urge" (transitive and intransitive), from Proto-Germanic *sturjan (cognates: Middle Dutch stoeren, Dutch storen "to disturb," Old High German storan "to scatter, destroy," German stören "to disturb"), from PIE *(s)twer- (1) "to turn, whirl" (see storm (n.)). Related: Stirred; stirring. Stir-fry (v.) is attested from 1959.
stir (n.)youdaoicibaDictYouDict
"commotion, disturbance, tumult," late 14c. (in phrase on steir), probably from a Scandinavian source, such as Old Norse styrr "disturbance, tumult," from the same root as stir (v.)). The sense of "movement, bustle" (1560s) probably is from the English verb.
