Choosing the Right Antonym for “Nice”
Antonyms are most useful when they reverse the same sense of “nice.” A word that works for kindness, pleasantness, friendliness, or an agreeable experience may sound wrong in a different context, even if a thesaurus places it nearby.
For “nice,” clarity matters more than variety. Read the completed sentence aloud and keep the original wording if an alternative changes the meaning or sounds unnatural.
