(a.) A work thrown up to intercept an enfilade, or reverse fire, along exposed passage, or line of work.

(a.) To deny formally, as what the opposite party has alleged. When the plaintiff or defendant advances new matter, he avers it to be true, and traverses what the other party has affirmed. To traverse an indictment or an office is to deny it.
(v. i.) To use the posture or motions of opposition or counteraction, as in fencing.
