Here's why:
* Suffixes: "-ness" and "-less" are suffixes that are added to the end of words. They have distinct meanings:
* "-ness" denotes a state or quality (e.g., happiness, sadness)
* "-less" indicates the absence of something (e.g., hopeless, careless)
* Word Formation: English words generally do not have two suffixes directly following each other.
