Q1  15
Q1 15

Question 1: The scientist gave a ___ explanation of how the experiment worked.

Question 1 options
'Scientific' is correct because the suffix '-ic' forms adjectives meaning 'having the nature or qualities of' a noun — here, 'science'. 'Science' is a noun, not an adjective. 'Scienceful' and 'scienceless' are not real English words.
Q2 15

Question 2: The children's behaviour at the party was completely ___. They ran around and ignored the rules.

Question 2 options
'Uncontrollable' is correct because the suffix '-able' forms adjectives meaning 'capable of being' something — 'uncontrollable' means it cannot be controlled. 'Uncontrolling', 'uncontrolled' and 'uncontrolment' do not use an adjective suffix correctly in this context.
Q3 15

Question 3: Adjective suffixes can be added to nouns or verbs to create adjectives.

Question 3 options
True because adjective suffixes change the grammatical function of the root word. For example, adding '-able' to the verb 'prevent' creates the adjective 'preventable', and adding '-al' to the noun 'region' creates 'regional'.
Q4 15

Question 4: What does the suffix '-less' express when added to a noun or adjective?

Question 4 options
'-less' expresses the absence or lack of something. For example, 'fearless' means without fear, and 'powerless' means without power. It does not indicate presence, possibility, or similarity.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • storm
  • powerful
  • The
  • damaged several houses
  • overnight.

Drag items or use arrows to arrange them in the correct order.

The correct order is 'The powerful storm damaged several houses overnight' because 'powerful' is an adjective formed with the suffix '-ful' modifying the noun 'storm', and it must come directly before the noun it describes.
Q6 15

Question 6: Which sentence uses an adjective suffix correctly?

Question 6 options
'The mountain air felt refreshful' is wrong ('refreshful' is not a word). 'She wore a beautiness dress' is wrong because '-ness' forms nouns, not adjectives. 'He gave a creatively answer' is wrong because 'creatively' is an adverb. 'The artist had a creative vision' is correct — 'creative' uses the suffix '-ive' to form a proper adjective.
Q7 15

Question 7: A student writes: 'The new road system is very use___.' Which suffix correctly completes the adjective meaning 'having no use'?

Question 7 options
'-less' is correct because it forms adjectives meaning 'without' or 'lacking' a quality — 'useless' means without use. '-ful' would create 'useful' (the opposite meaning), '-able' would create 'useable' (able to be used), and '-ish' would create 'useish' which is not a real word.
Q8 15

Question 8: Which sentence uses the suffix '-ous' correctly, NOT the suffix '-ful'?

Question 8 options
'-ous' means 'full of or having the quality of' and forms adjectives like 'dangerous'. 'Dangerful', 'Dangerable', and 'Dangerish' are not real English words — only '-ous' correctly attaches to 'danger' to form a standard English adjective.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • generous
  • donation
  • helped many
  • homeless people.
  • Her

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Her generous donation helped many homeless people' because 'generous' (suffix '-ous') modifies 'donation' and 'homeless' (suffix '-less') modifies 'people', both adjectives correctly precede their nouns.
Q10 15

Question 10: The manager needs someone ___ for this important role. She wants a person who can be trusted with responsibilities.

Question 10 options
'Responsible' is correct because the suffix '-ible' (a variant of '-able') forms an adjective meaning 'capable of being relied upon'. 'Responsibility' is a noun, 'responsibly' is an adverb, and 'responsibilious' is not a real word.
Q11 15

Question 11: Which statement about the suffix '-ful' is true?

Question 11 options
'-ful' is added to nouns to create adjectives meaning 'full of' or 'having a particular quality', as in 'beautiful' (beauty + -ful) and 'powerful' (power + -ful). It does not create nouns or verbs, and it does not mean 'without'.
Q12 15

Question 12: The coach described the player as 'aggress___'. Rewrite as a complete adjective: 'The player was very ___.'

Question 12 options
'Aggressive' is correct because the suffix '-ive' attaches to the root 'aggress-' to form an adjective meaning 'tending toward aggressive behaviour'. 'Aggression' is a noun, 'aggressful' is not a real word, and 'aggressless' would mean 'without aggression' — the opposite meaning.
Q13 15

Question 13: Match each sentence to the adjective suffix rule it demonstrates.

Question 13 options
The medicine is not suitable for children under five.
The mysterious letter arrived with no name on the envelope.
The careless worker left tools all over the floor.
He gave a sheepish grin when caught eating the last biscuit.
Suffix '-ous': full of or having a particular quality
Suffix '-less': without or lacking a quality
Suffix '-ish': having a mild or approximate quality of
Suffix '-able': capable of or worthy of

Select an item on the left, then tap its match on the right.

Each adjective suffix has a specific meaning: '-able/-ible' = capable of; '-ous' = full of/having a quality; '-less' = without; '-ish' = having a mild or approximate quality of.
Q14 15

Question 14: When the suffix '-ness' is added to an adjective ending in '-y', the spelling always stays the same (e.g. 'happy' becomes 'happyness').

Question 14 options
False because when '-ness' is added to a word ending in '-y', the '-y' changes to '-i' before the suffix. So 'happy' becomes 'happiness', not 'happyness'. This is a standard spelling rule that applies to many '-y' ending words.
Q15 15

Question 15: Which sentence uses the correct adjective to describe something that resembles a child in an innocent, sweet way — NOT in a negative, immature way?

Question 15 options
'Childlike' (suffix '-like') suggests innocent resemblance to a child and carries a positive connotation. 'Childish' (suffix '-ish') implies immaturity or silliness in a negative way. Both are grammatically correct adjectives, but the meaning and register differ based on their suffixes.
