causing damage, injury, or bad effects
Causing bad results or hurting someone or something, or likely to do so.
Vzorec užití:
[something] is harmful to [someone/something]
Častá chyba:
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.
Synonyma
damaging (Very close in meaning; can often replace "harmful" when talking about physical or non-physical negative effects.)
|
dangerous (Suggests a stronger risk of serious injury or death; not always about slow or indirect bad effects.)
|
detrimental (More formal; often used for long-term or indirect negative effects, especially in writing.)
Antonyma
harmless (Direct opposite; means something does not cause damage or injury.)
|
beneficial (Opposite in terms of result; it brings good effects instead of bad ones.)
|
safe (Opposite in terms of risk; suggests there is little or no danger or bad effect.)
