thwart
As a verb, this word carries a strong sense of active interference. It suggests a decisive action that blocks a goal or ruins a scheme, often implying a victory for the person doing the thwarting. It is more forceful than simply preventing something, as it often involves defeating an opponent's specific intent. In a nautical context, the word describes a physical orientation of being crosswise. The noun form refers specifically to the structural seats in a boat, which are placed perpendicular to the keel. This physical crossing mirrors the verb's sense of blocking or cutting across a path.
