Puddle
A puddle is a small mass of liquid, usually water, uncontained on a surface. It can form either in depressions in the surface, or directly upon the flat surface, held together by surface tension. A puddle is generally considered to be small enough to step over or shallow enough to walk through, and too small to traverse with a boat.
Puddles commonly form during rainstorms, and can cause problems for transport, especially when combined with cold conditions to form patches of ice, which are highly slippery and difficult to see.
