Etymology

Probably from Middle English yerk (“sudden motion”) and Middle English yerkid (“tightly pulled”), from Old English ġearc (“ready, active, quick”) and Old English ġearcian (“to prepare, make ready, procure, furnish, supply”). Cognate with Scots yerk (“to jerk”). Related also to English yare (“ready”).

Denominal verb of jerky, itself borrowed from Spanish charqui, from Quechua ch'arki.
