Put-down, referring to something that undermines someone's dignity, can have several antonyms, depending on the situation. A supportive word or phrase that uplifts someone's esteem is the direct opposite of a put-down. Compliment, praise, encouragement, and admiration are all antonyms that can be used to negate the damaging effects of a put-down. In situations where a put-down is used to mock or ridicule someone, antonyms such as respect, honor, and dignity can be used to counteract the negativity. Additionally, if the context involves making someone feel important or valued, antonyms such as appreciation, gratitude, and recognition can be used instead of a put-down.
