Collar originates from Old French *coler* (meaning to put around the neck), which is derived from Latin *collare* (meaning a neckband or collar). The word refers to a band or piece of material that encircles the neck.
Think of a 'neckband' ('collare') that goes 'around' ('coler') your neck — that's what a collar is.
