What's the difference between i.e. and e.g.?
late 14c., "haul up and fasten with a rope" (v.), from Middle Dutch trisen "hoist," from trise "pulley," of unknown origin. Hence at a tryse (mid-15c.) "in a very short time," literally "at a single pluck or pull." The Middle Dutch word is the source of Dutch trijsen "to hoist," and cognate with Middle Low German trissen (source of Danish trisse, German triezen); its ultimate origin is unknown.
