How to Say "i invented" in Spanish
The Spanish word for “i invented” is “inventé” — A2 level. This is a very common word in everyday Spanish.

The Past Tense Accent
The accent mark on the 'é' is very important. It tells the listener that the action happened in the past and that 'I' (yo) was the one who did it.
Missing the Accent Mark
Mistake: “Using 'invente' when you mean 'I invented'.”
Correction: Use 'inventé'. Without the accent, 'invente' usually sounds like a command or a wish (like 'I hope he invents').
