User talk:Exclusive Words

I write stories and songs, scripts for ads etc Often words and names chosen for subjects, titles or items, even thinking it does not exist actually often later is confirmed as already in use by a writer, director etc.

One such example is Yucky Doodles (I created my own concept around this)it was spelled Yucky Doodle, which I used for a script  Before publishing it I discovered it was also a name for a Donald Duck character (Didn't know - some people in line of their work may obviously think alike ) Now I have a word that I gave meaning to according to my own description & discretion which obviously could be used by others but I need it to be exclusively assigned for public use in stories etc as the creator thereof to myself. If I give the details and content to WIKIPEDIA will this be a safe avenue and be recorded as that obviously excepting that it must sound and have acceptable usage criteria to others, but this I will be able to use in my own way for educational, advertising & other communication purposes. OBVIOUSLY, I have searched this word and it came back as no results - the word does not exist HELP ME
