The term "making as if" refers to pretending or feigning a particular action or behaviour. Its antonym, on the other hand, would be the act of actually doing or performing the action. For instance, a person who is "making as if" to be sick would be simulating or pretending to be ill, whereas the actual act of being ill would be the antonym. Similarly, if someone is "making as if" to be happy, they would be pretending to be happy, but genuinely feeling sad or depressed would be the antonym. Antonyms for "making as if" include sincerity, genuineness, and authenticity.
