This Grade 4 English worksheet introduces students to the suffixes -able and -ible, helping them understand how these endings change root words into adjectives that describe possibility, capability, or suitability. Through engaging exercises, learners explore words such as readable, visible, breakable, flexible, and comfortable while strengthening their vocabulary and grammar awareness.
The worksheet uses clear examples and structured activities so students can easily recognize how suffixes work in everyday language. Children learn that words ending in -able or -ible often mean “can be” or “able to be,” which helps them decode new vocabulary while reading.
