The phrase "be match for" implies being capable of handling or defeating something, so antonyms would be words or phrases indicating incapability, unsuitability, or inferiority. "No match for" suggests being unable to compete or withstand, "ill-equipped for" indicates lack of preparation or resources, "inadequate for" denotes insufficiency or ineffectiveness, and "unsuited for" implies being incompatible or inappropriate. Other antonyms may include words like "inferior," "disadvantaged," or "outclassed." It is important to note that antonyms are not just opposite words, but convey a contrasting meaning, so selecting the appropriate term based on context is crucial.
