Here's how it changes the word:
* It transforms the word into a superlative form, indicating the highest level of the quality:
* Example: "tall" (adjective) becomes "tallest" (superlative)
* Example: "quickly" (adverb) becomes "quickest" (superlative)
* It implies a comparison among three or more entities: The "-est" ending indicates that the entity being described possesses the quality to a greater degree than all other entities in the comparison group.
Here are some examples:
* Tall: This is the regular adjective.
* Taller: This is the comparative form, indicating that one entity is taller than another.
* Tallest: This is the superlative form, indicating that one entity is taller than all others.
Remember:
* "-est" is usually added to adjectives and adverbs that end in a consonant sound.
* For adjectives that end in a vowel sound or "y" preceded by a consonant, "-est" is replaced with "-iest."
* There are some irregular superlatives, such as "best" (from "good") and "worst" (from "bad").
