Fascinating Fact:

Suffix able or ible shows possibility, washable shoes survive rain, audible music carries 20 metres down the hall.

In KS3 English, you study how suffixes change words. The endings -able and -ible often mean “capable of.” Choosing the right one improves clarity, spelling accuracy, and formal style in your writing. Examples include leaf → leaves and roof → roofs.

  • Suffix: Letters added to the end of a word to change its meaning or word class, such as -able.
  • Adjective: A word that describes a noun, for example washable or audible.
  • Root word: The base form to which endings are added, for example comfort in comfortable, or roofroofs.
What is the difference between -able and -ible?

Both mean “capable of.” A common guide is: if the base is a complete English word, use -able (comfortcomfortable); if not, -ible is more likely (posspossible).

How can I decide which suffix to use in KS3 English?

Check the root and a dictionary. Try the pattern: whole root plus -able (relyreliable), while many Latin-based roots take -ible (credible, visible).

Do -able and -ible words form adverbs with -ly?

Yes. Many become adverbs by adding -ly, for example reliablereliably, possiblepossibly.
