Here are some examples:
* Homeless: Without a home
* Hopeless: Without hope
* Effortless: Without effort
* Fearless: Without fear
* Meaningless: Without meaning
* Sleepless: Without sleep
There are a few things to remember about using "-less":
* The noun it attaches to must be a thing that can be absent. For example, you can be "hopeless" because hope is something you can lack, but you can't be "chairless" because chairs are objects, not qualities.
* Sometimes "-less" is added to verbs to form adjectives. This usually indicates the absence of the action of the verb. For example: "speechless" (unable to speak), "thoughtless" (lacking thought).
The "-less" suffix is a versatile tool for creating new adjectives and describing things that lack a particular quality.
