What is your definition of single word

 

[noneisnone]

if you are looking for such words there is literary a shit ton dropping everyday
when you see someone seeking a one word .com they are looking for a word that is commonly used in everyday life and that can be of use for a brand or a business

personal example i own Limnic.com which is a word on it own but i it will never sell as a "one word .com" instead i sell it as brandable.

before buying a one word .com ask yourself if a 6 year old knows what it mean

Somewhat. The US spelling is self centered. And generally is divided with a space.
