What does spar mean?
A spar is a strong, elongated pole used to support or reinforce a structure, especially the rigging of a sailing vessel. By extension, the word can refer to a practice boxing match, since fighters engage in a spar. As a verb, spar means to box, quarrel, or exchange verbal blows; in negotiations, it can also mean to offer or concede something in a limited or token way. The word therefore carries a mild sense of contest and testing. It is especially useful in nautical, engineering, and sporting contexts, where it describes both the physical supports of a larger structure and the informal contests that develop between opponents. In conversation, using spar to describe an argument adds a vivid image of two people testing one another without necessarily implying a serious dispute.
