Key Rules
- Synonyms are not always exactly the same: "Big" and "large" are very close, but "big" sounds more casual and "large" sounds a bit more formal. For P2, both are correct.
- Antonyms are exact opposites: If something is hot, the opposite is cold -- not "warm". Pick the word that is the most opposite.
- Read the whole sentence first: Before choosing a synonym, read the sentence to make sure the word fits. "She began to cry." The synonym is "started", not "opened".
- One word can have more than one antonym: "Old" can mean the opposite of "young" (for people) or "new" (for things). The sentence tells you which one to pick.
Common Mistakes
| Wrong | Right | Why |
|---|---|---|
| Picking "cold" as a synonym for "hot" | Picking "boiling" or "burning" as a synonym for "hot" | "Cold" is the opposite of "hot", not the same meaning |
| Saying "happy" and "excited" are antonyms | Saying "happy" and "sad" are antonyms | "Excited" is not the opposite of "happy" -- "sad" is |
| Choosing a synonym that does not fit the sentence | Reading the sentence first, then choosing | A synonym must make sense in the sentence |
| Thinking "short" is always the antonym of "long" | Checking the sentence context | "Short" is the antonym of both "tall" and "long" -- the sentence tells you which |

Tip: If the question says "same meaning", look for a synonym. If the question says "opposite meaning", look for an antonym. The question always tells you which one to find!
Practice Tips
- Try swapping the word: Put the answer word into the sentence. Does it still make sense? If yes, it is a good synonym. "The cat is big." Try "The cat is large." -- yes, it works!
- Think of opposites in pairs: Learn antonyms as pairs -- big/small, happy/sad, hot/cold. When you see one word, the opposite should come to mind right away.
- Use the sentence as a helper: The words around the blank help you choose the right synonym. "She felt very ___ when she lost her toy." The sentence is about losing something, so the answer is a sad word, not a happy word.
