词源
From Middle English spanne, from Old English spann, from Proto-Germanic *spannō (“span, handbreadth”), from Proto-Indo-European *(s)pend- (“to stretch”). Cognate with Dutch span, spanne, German Spanne. The sense “pair of horses” is probably from Old English ġespan, ġespann (“a joining; a fastening together; clasp; yoke”), from Proto-West Germanic [Term?]. Cognate with Dutch gespan, German Gespann.
