Here's why:
* Suffix: A suffix is a word part added to the end of a word to change its meaning or grammatical function.
* Ful: This suffix is often used to create adjectives, meaning "full of" or "characterized by." For example:
* Beautiful (full of beauty)
* Joyful (full of joy)
* Truthful (full of truth)
* Less: This suffix creates adjectives that mean "without" or "lacking." For example:
* Hopeless (without hope)
* Careless (lacking care)
* Ruthless (without ruth)
