A small problem or obstacle that complicates a situation. We hit a snag in our plans when the venue was double-booked.
A sharp or rough projection, especially one on a tree or in a piece of wood. Be careful of the snag on that branch; it could tear your clothes.
A dead tree or part of a tree that is still standing. The old snag in the forest was a popular spot for woodpeckers.
A tear, pull, or run in a piece of fabric caused by catching on something. There's a snag in my new sweater where it caught on a nail.
(Australia, informal) A sausage, especially one cooked on a barbecue. Could you throw a few snags on the barbie for lunch?
A submerged tree trunk, branch, or other obstruction hidden under water that poses a hazard to navigation. The canoe capsized after hitting a snag just below the surface.
