The '-mente' Ending
Just like '-ly' in English, adding '-mente' to the end of a Spanish adjective turns it into a word that describes how or to what extent something is. Since it's an adverb, it never changes its ending to match masculine or feminine words.
Where to place it
You usually place 'potencialmente' right before the adjective it is describing, such as saying 'potencialmente útil' (potentially useful).
The 'Eventually' Trap
Mistake: “Using 'eventualmente' to mean 'potentially'.”
Correction: In Spanish, 'eventualmente' means 'by chance' or 'occasionally.' If you want to say something has the *capacity* to become something else, always use 'potencialmente'.
