Creating a new word
What are the criteria to adopt new words into English?
What if I want to use the term supertibi somewhere accompanying superego? We have superego in dictionaries all over the world, but supertibi is a new term morphologically based on the same components (super = great, tibi = you, ego = I) and it is not used anywhere. How can we coin new terms? Is there a formulated procedure?
For citizens of the UK and Commonwealth countries, applications are made to HM English Academy in London and the time periods are longer (3 years minimum, I believe) and there's a £100 application fee.
There are lawyers who specialize in this kind of thing. Contact your local Bar association for a referral.
If you're serious about coining a new word, I urge you to read this first.
