Hi,
What does these sentences mean?
1: Their frolic in the surf threatened to become ugly.
In the above sentence I can't understand the meaning of ugly.
2: One of the meanings of morose is ''showing a brooding ill humor''.
In the above sentence I think ill humor means bad temper and I also know the meaning of brooding but can't understand the meaning of phrase?? ''brooding ill humor'' as a whole.
Sincerely,
vijay
