Sample questions
Question 1 — Easy
Priya felt ___ when she lost her library book.
Answer: The prefix 'un-' is added to the base word 'happy' to make 'unhappy'. The prefix 'un-' meaning 'not' is simply placed before the base word without changing its spelling. Options B, C, and D all contain misspellings of either the prefix or the base word.
Question 2 — Medium
Priya felt ___ when she lost her library book. Choose the correct spelling.
Answer: The prefix 'un-' is added to the base word 'happy' to make 'unhappy'. The prefix 'un-' never doubles its final letter, and the base word 'happy' keeps all its letters. 'Unhapy' drops the double-p, 'unnhappy' wrongly doubles the n, and 'unhappey' adds an incorrect vowel at the end.
Question 3 — Hard
Choose the correct spelling to complete the sentence. Mia's ___ at remembering animal names amazed her class.
Answer: The suffix '-ness' is added to the base word 'clever' to form 'cleverness'. No letters are dropped or changed when '-ness' is added to a word ending in a consonant. Options A, C, and D all misspell the suffix '-ness'.
