Adjective Formation Advanced Exercises
B2 Level
English Exercises is teacher-led by Charlie. About the teacher · How content is made
The main challenge is spelling. A final -e may disappear before a suffix, y may change to i, and some words have less predictable forms, such as practice becoming practical. Do not add a negative prefix just because one is possible; the meaning of the full sentence decides. These B2 questions prepare you to notice word class, adjective endings, and meaning at the same time, which is exactly what advanced word formation tasks require. Always reread the completed phrase to check that the adjective sounds natural before the noun or after the verb.
Quick Rule
base word + adjective suffix, with a negative prefix only when the sentence needs "not"
- 1.BELIEVE -> unbelievable: an unbelievable story
- 2.COMFORT -> comfortable: a comfortable chair
- 3.LOGIC -> logical: a logical answer
- 4.RELY -> reliable: reliable information
