🌟 Explanation:

Irregular plurals don’t follow the usual rules (like adding -s or -es). Instead, they have unique forms:
- Child → Children
- Foot → Feet
- Person → People
- Shelf → Shelves
- Calf → Calves
- Criterion → Criteria
- Man → Men
- Leaf → Leaves
- Wolf → Wolves

Some words like tuna remain the same in plural when used as a food item.

This worksheet helps students recognize these irregular patterns, which are common in English grammar.
