The plural of 'mouse' is:

**The reasoning** English has two ways of forming plurals: **regular** and **irregular**. Regular nouns just add "-s" or "-es" (book → books, box → boxes). But some nouns inherited ancient plural forms that don't follow this pattern — these are **irregular plurals**. "Mouse" is one of those special irregular nouns. It comes from Old English, where the plural was "mys" (pronounced "meese"). Over centuries, this evolved into **mice**. Other animals follow similar patterns: goose → geese, louse → lice. So the answer is **B) mice** — it's simply one of those words you must memorize because it doesn't follow the regular rule. **Why the wrong options tempt you** - **A) mouses** — This looks right because most plurals add "-s". Your brain wants to apply the common rule, but mouse is an exception. - **C) meeses** — Some students confuse this with "geese" (the plural of goose), but that's a different word entirely. - **D) mouse** — A few nouns stay the same in plural (like sheep), but mouse isn't one of them. **Quick takeaway** Irregular plurals like mouse → mice don't follow rules — memorize them alongside man → men, foot → feet, and child → children.
