My eldest was talking the other day about the fact that we have not completed her registration for the next year in school. She asked us if we could "registrate" her as soon as possible.
Obviously we shared the wisdom of our years' of experience in speaking English and told her that the correct word is "register".
I looked up some online dictionaries and I see that there is a word "registrate" which means: "to select and combine pipe organ stops"
Live and learn.
Other online dictionaries tell me that it is also a transitive verb meaning to register.
Live and learn again!
