However, I can tell you that "est" is a common suffix used to form the superlative form of adjectives and adverbs in English.
Here's how it works:
* Adjectives: "est" is added to the end of most adjectives to indicate the highest degree of a quality.
* Example: "tall" becomes "tallest"
* Adverbs: "est" is used less commonly with adverbs, but it can indicate the highest degree of manner or intensity.
* Example: "fast" becomes "fastest"
Important Notes:
* Some words already have the suffix "est" as part of their base form (e.g., "newest").
* Irregular adjectives and adverbs have special superlative forms (e.g., "good" becomes "best").
* For adjectives ending in "-y," the "y" is usually changed to "i" before adding "est" (e.g., "happy" becomes "happiest").
