Let's solve the worksheet step by step, following the rules provided.
---
Part 1: Nouns ending in Y
Rule:
- If a noun ends in
Y and the letter before Y is a
consonant, change
Y to I and add
ES.
Example: *fly → flies*
- If a noun ends in
Y and the letter before Y is a
vowel, just add
S.
Example: *holiday → holidays*
Now apply this rule:
| Word | Plural Form |
|----------|-------------|
| lady |
ladies (Y preceded by consonant 'd' → change Y to I, add ES) |
| copy |
copies (Y preceded by consonant 'p' → change Y to I, add ES) |
| toy |
toys (Y preceded by vowel 'o' → add S) |
| army |
armies (Y preceded by consonant 'm' → change Y to I, add ES) |
| country |
countries (Y preceded by consonant 'r' → change Y to I, add ES) |
| fairy |
fairies (Y preceded by consonant 'r' → change Y to I, add ES) |
| party |
parties (Y preceded by consonant 'r' → change Y to I, add ES) |
| key |
keys (Y preceded by vowel 'e' → add S) |

Part 2: Nouns ending in F or FE
Rule:
Change
F or
FE to
V and add
ES.
Examples:
- shelf → shelves
- life → lives
Apply this rule:
| Word | Plural Form |
|--------|-------------|
| knife |
knives (F → V + ES) |
| half |
halves (F → V + ES) |
| loaf |
loaves (F → V + ES) |
| elf |
elves (F → V + ES) |
| shelf |
shelves (F → V + ES) |
| leaf |
leaves (F → V + ES) |
> Note: "Loaf" becomes "loaves" — although it ends in 'f', the plural follows the same pattern as "shelf".

Part 3: Convert plurals to singular
Now reverse the process:
| Plural Form | Singular Form |
|-------------|----------------|
| families |
family (remove ES, change I back to Y) |
| lives |
life (remove ES, change V back to F) |
| calves |
calf (remove S, note: irregular, but "calves" comes from "calf") |
| cities |
city (remove S) |
> Explanation:
> - "families" → remove "ES", change "I" back to "Y" →
family
> - "lives" → remove "ES", change "V" back to "F" →
life
> - "calves" → singular is
calf (irregular, but common knowledge)
> - "cities" → remove "S" →
city
