Correct spelling


Correct spelling, explanation: the word provider comes from the verb provide. It’s an agent noun, which means that is derived from another word denoting an action. The suffix -er means someone or something performing a particular action. The suffix -or also creates an agent noun, but not in this case. Provider is the only correct form and providor is just a mistake.

Incorrect spelling


Incorrect spelling, explanation: providor is a non-existent word, so you should be careful not to use it in any sentence. The only correct version of this noun is provider. It consists of two elements: a root and a suffix -er, a very common ending that is used to name someone or something performing an action. It’s easy to make a mistake because the suffix -or usually denotes a profession or a performer as well.
