Rules to Keep in Mind
For Synonyms
Some opposite words for kidsmean the same, but their usage depends, like large and big mean the same thing, but you would say she has a big heart, not a large heart.
Always read your sentence out loud after swapping a word. Most of times, if it sounds natural, it works.
For Antonyms
Antonyms must always match the same word type. If your original word is an adjective, its antonym must also be an adjective, not a noun or verb.
Avoid using random opposites that make no sense together. As the contrast should always add meaning to your sentence.
