late Middle English (as a noun): from Middle Low German, literally ‘track’, of West Germanic origin; related to tread. Early senses included ‘course, way of life’, which gave rise in the 16th century to ‘habitual practice of an occupation’, ‘skilled handicraft’. The current verb senses date from the late 16th century.
