Words Ending in -ably and -ibly — Interactive Lesson (KS2)

Is it ‘comfortably’ or ‘comfortibly’? This 11-slide interactive lesson teaches words ending in -ably and -ibly using a simple root-word rule.

Mastering Words Ending in -ably and -ibly in KS2 English

Pupils learn that -ably and -ibly are adverb suffixes formed from -able and -ible adjectives, apply the rule that a complete root word takes -ably while an incomplete root takes -ibly, and spell common words correctly. They see that adore becomes adorably and comfort becomes comfortably because both are complete words, while terr- is not a word on its own, so it takes -ibly, as in terribly. Pupils also learn key exceptions to the rule, such as sensibly, responsibly and flexibly.
