Nono, you ought to know English is now spoken by 3 times as many non-native speakers (for whom it was not their "mother tongue"), don't presume someone with a non-Anglo surname, or even an admitted hispanic would not be capable of catedra on its correct usage, particularly when the term is of latin etymology. Intervention is of latin origin, from intervenio (to come between). It also refers to interfere. Intervene is a word in English that refers to "step in or settle" (in its 3rd usage). It means to come or be between, the prefix inter means "among" and venio "to come". The term applies to abstract concepts like time (as in the years that intervened), it also means "to get in the way of" (as in if nothing unexpected intervenes).
