How to Say "incorrect" in Spanish
The most common Spanish word for “incorrect” is “falsa” — use 'falsa' when referring to information, statements, or claims that are factually wrong or untrue..
falsa
/fal-sa//ˈfalsa/

Examples
La información que recibimos era completamente falsa.
The information we received was completely false.
Tienes que borrar esa idea falsa de tu cabeza.
You have to erase that wrong idea from your head.
Adjective Agreement
Since 'falsa' is the feminine form, it must be used to describe feminine nouns, like 'la respuesta' (the answer) or 'la promesa' (the promise).
Confusing Gender
Mistake: “El respuesta es falso.”
Correction: La respuesta es falsa. (Remember 'respuesta' is feminine, so the adjective must match.)
equivocada
eh-kee-voh-KAH-dah/ekiβoˈkaða/

Examples
Creo que tu amiga está equivocada sobre la hora de la reunión.
I think your friend is mistaken about the time of the meeting.
La dirección que escribiste en el sobre está equivocada.
The address you wrote on the envelope is wrong.
Si piensas que es fácil, estás equivocada. Necesitas más práctica.
If you think it's easy, you are wrong. You need more practice.
Feminine Agreement
Since this word ends in '-a', it is the feminine form. Use it only when describing feminine nouns (like 'mujer', 'idea', 'respuesta').
State vs. Identity (Estar)
Almost always use 'estar' (to be) with 'equivocada' because it describes the temporary state of having made a mistake, not a permanent quality of the person.
Using the Masculine Form
Mistake: “La niña es equivocado.”
Correction: La niña está equivocada. Remember to match the ending to the subject (niña is feminine, so use -a).
