suffix ness, full and less

This language lesson is designed for 6 to 12-year-old children. It guides the child to learn the meanings of the new words formed when a suffix is added to the base word.

What is a Suffix?

A suffix is a word or a letter that is placed at the end of another word. Adding a suffix changes the meaning of the base word and forms a new word. For example, ‘al’ means action, and when added at the end of denying becomes denial and changes its meaning.

Watch this video to understand how a suffix can convert a word into a noun, verb, adverb, or adjective. It can also make a transition in the degree of an adjective or in the tense of a verb.

The most common suffixes are S, ES, ED, and ING. These four suffixes are the most useful and important to learn as they are most frequently used in different language lessons.

Encourage the child to practice the concept of suffixes with different English words and help them add new words to their vocabulary.
