The correct spelling of "advocators" is actually "advocates." The pronunciation of the word is [ˈædvəkeɪts]. The IPA phonetic transcription reveals that the "o" and "r" in "advocators" are incorrect, whereas the correct spelling, "advocates," contains an "a" and "t" at the end of the word. It's important to use correct spelling to effectively communicate with others, and to avoid any confusion or misunderstandings.
The word advocators does not have an etymology on its own because it is not a recognized English word. It appears to be a derivative of the noun advocate with a suffix added to it. Advocate comes from the Latin word advocatus, which means one called to aid or one who intercedes on behalf of another. The term has its roots in the verb advocare, which combines ad (meaning to) and vocare (meaning to call). However, advocators is not a standard form, and a more commonly used plural for advocate is advocates.
