Antonym of EXPAND.

**The reasoning** An **antonym** is a word that means the **opposite** of another word. EXPAND means to become larger, to increase in size or volume — think of a balloon inflating or a business growing bigger. The opposite action? Making something **smaller** or **reducing** its size. That's exactly what SHRINK means — like clothes after hot washing, or a balloon deflating. They're perfect opposites: expand ↔ shrink. **Why the wrong options tempt you** - **Grow** is actually a *synonym* (similar word) to expand, not an opposite - **Widen** means to make broader — another synonym, just focusing on width - **Open** might *feel* opposite in some contexts (like opening vs closing a box), but it's not the direct opposite of expand in meaning All three traps are words that either mean the same thing or are loosely related, banking on you not thinking carefully about what "opposite" truly means. **Quick takeaway** For antonym questions, ask yourself: "What action *reverses* or *undoes* this word?" — expand makes bigger, shrink makes smaller.
