Here are some examples:
* Biggest: Largest in size.
* Longest: Most extended in length.
* Strongest: Having the most strength.
* Happiest: Feeling the greatest joy.
How it works:
* The suffix "-gest" is usually added to the root word after removing the final "e" or "y" (sometimes changing the "y" to "i").
For example:
* Big + est = Biggest
* Long + est = Longest
* Happy + iest = Happiest
Important Note: Not all superlative adjectives and adverbs use "-gest." Some use "-est" or "-most."
