What does Anachroism Mean? or I think I Made a New Word

I was making a comment online and I used the term "print" instead of "publish". ...an anachronistic use of a verb that I caught upon editing. I wanted to use the term "anachroism" to give a name to my habit (malady) of doing so and learned that it's not a word, until now.

a·nach·ro·ism

/əˈnakro,izəm/ 

A linguistic condition characterized by archaic terminology references in speech.
