Error frecuente:
Learners often say "harmful for" instead of "harmful to". The usual pattern is "harmful to [someone/something]", as in "harmful to your health" or "harmful to the environment". Learners may also confuse "harmful" and "dangerous"; "dangerous" suggests a strong and often immediate risk, while "harmful" can be slower or more indirect.
