Key Notes on Plurals:

1. Regular nouns: Most plurals are formed by adding -s (e.g., hats, days, desks).
2. Nouns ending in s, x, ch, sh, or z: Add -es (e.g., boxes, brushes, churches).
3. Nouns ending in a consonant + y: Change y to ies (e.g., families, puppies).
4. Nouns ending in f or fe: Usually change to -ves (e.g., knives, wives), though some take -s (e.g., roofs, beliefs).
5. Irregular plurals: Follow unique patterns (e.g., man → men, tooth → teeth).
6. Unchanging nouns: Some nouns remain the same in singular and plural (e.g., deer, means).
7. Compound nouns: Pluralize the main part of the compound (e.g., mothers-in-law, passers-by).
