Here's how it works:
* It's added to a noun or adjective to create a new adjective.
* The new adjective describes something that does not have the quality or characteristic represented by the original noun or adjective.
Here are some examples:
* "Homeless" means without a home.
* "Hopeless" means without hope.
* "Worthless" means without worth.
* "Fearless" means without fear.
* "Thoughtless" means without thought.
The suffix "-less" can be used to create a wide range of words that describe the absence of various qualities, traits, or objects.
