sip

Inherited from Middle English sippen, of uncertain origin. Compare with Low German sippen (“to sip”). Possibly from a variant of Middle English suppen (“to drink, sip”) (see sup) or perhaps from Old English sipian, sypian (“to take in moisture, soak, macerate”), from Proto-Germanic *sipōną (“to drip, trickle”), from Proto-Indo-European *seyb- (“to pour out, trickle, leak out”). Compare also Old High German supfen (“to drink, sip”), from Proto-Germanic *sūpaną (“to sip, intake”).
