adjective （限义项2）词源
late 16th cent. (in sense 2)： probably of Scandinavian origin. The early sense 'stump sticking out from a tree trunk' gave rise to a US sense 'submerged piece of timber obstructing navigation', of which sense 1 is originally a figurative use. Current verb senses arose in the 19th cent.
