Lesson 24: Suffix -est

Discover How the Suffix -est Helps Us Show the Greatest Amount

As children become stronger readers, they begin to notice that many words are made up of meaningful parts called morphemes. In this lesson, we introduce the suffix -est, a common ending added to adjectives to show that someone or something has the most of a quality. The suffix -est is used when comparing three or more people, animals, places, or things.

Learning common suffixes helps children understand grammar, build vocabulary, and improve both reading and writing. Whether you're a parent, teacher, tutor, or homeschool educator, this free lesson provides engaging resources to support children's growing understanding of word structure.

Morpheme Spotlight: The Suffix -est

A suffix is a word part added to the end of a base word. Suffixes can change the meaning or the grammar of a word.

The suffix -est is added to many adjectives to show that one person, animal, place, or thing has the most of a quality when comparing three or more.

Examples include:

• big → biggest

• fast → fastest

• long → longest

• tall → tallest

For example:

• The rabbit is fast.

• The cheetah is faster than the rabbit.

• The falcon is the fastest animal in the race.

Notice that adding -est changes the adjective to show the highest degree of a quality.

Learning the suffix -est helps children understand comparisons, describe things more precisely, and use richer language when speaking and writing.
