ANSWER KEY & EXPLANATIONS
1 (a) keys
Explanation: * Correct (Key): (a) ‘Keys’. The word ends in a vowel + y (e-y), so we simply add ‘-s’. The sentence says “There are three of them”, requiring a plural noun.
- Common Mistake: (b) ‘Keies’ is a spelling mistake where learners over-apply the ‘-ies’ rule.
- Structural Error: (c) ‘Key’ is singular, contradicting the number “three”.
2 (b) toys
Explanation: * Correct (Key): (b) ‘Toys’. Vowel + y (o-y) simply takes an ‘-s’.
- Common Mistake: (a) ‘Toies’ is an incorrect spelling.
- Structural Error: (c) ‘Toy’ is singular, but “two” requires a plural noun.
3 (c) boys
Explanation: * Correct (Key): (c) ‘Boys’. Vowel + y (o-y) takes an ‘-s’.
- Common Mistake: (b) ‘Boies’ is an incorrect application of the ‘-ies’ rule.

- Structural Error: (c) ‘Keies’ is an incorrect spelling.
6 (a) diaries
Explanation: * Correct (Key): (a) ‘Diaries’. The word ends in a consonant + y (r-y), so we drop the ‘y’ and add ‘-ies’.

- Structural Error: (b) ‘Diary’ is singular, but the number is “two”.

- Common Mistake: (a) ‘Copies’ is plural, which contradicts “one”.
- Structural Error: (c) ‘Copys’ is an incorrect plural spelling anyway.
14 (c) monkeys

GRAMMAR POINTS TO REMEMBER
To get your lost items back, you must tell the receptionist exactly how many things are missing! When counting nouns that end in the letter “y”, you need to look at the letter right before it:
1 The Vowel + Y Rule: If the letter before the “y” is a vowel (a, e, i, o, u), you just add -s. Never drop the ‘y’!
- Examples:
- key -> keys
- toy -> toys
- day -> days
- monkey -> monkeys
2 The Consonant + Y Rule: If the letter before the “y” is a consonant (like p, r, t, l), you MUST drop the ‘y’ and add -ies.
- Examples:
- copy -> copies
- city -> cities
- family -> families
- puppy -> puppies
3 Singular vs. Plural Logic: Always match the noun to the number. If you lost “one key”, use the singular. If you lost “three keys”, use the plural. Using the wrong form can confuse the person helping you!
