Veer comes from Middle French 'virer' ('to turn'), of uncertain origin, possibly from a blend of Latin 'gyrare' ('to turn') and 'viria' ('bracelet'). The nautical sense influenced later use. In current use it is a verb and noun meaning "to change direction or course suddenly". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The uncertainty belongs to the etymology itself and should be kept: the older ancestry is not presented as more secure than it is. A central historical form is Middle French virer. The semantic development is therefore important as well as the form: the word moves from the older concrete, technical, or literal setting into the present figurative or specialized sense.
