Pretty much this. A semantic error is also called a logic error. A
program with a semantic error will not crash or terminate abnormally,
but it will not produce the output that you want.

Semantic errors are much harder to catch than syntax errors, because
programs with semantic errors are still valid programs in the
language. A syntax error makes the program invalid, which means the
computer can easily identify it. It's up to you to identify semantic
errors.
