Frequently Asked Questions
Is 'falla' the same as 'fallo'?
No, they are very close but used differently. 'La falla' (feminine) usually means a mistake, flaw, or defect (like a technical problem). 'El fallo' (masculine) usually means a ruling or verdict (like a judge's decision) or, less commonly, a minor error.
How do I know if 'falla' is the noun or the verb?
Look at the words around it! If it has 'la' or 'una' in front of it ('la falla'), it is the noun (the mistake). If it is used after a subject like 'él,' 'ella,' or 'el motor,' it is the verb form (he/she/it fails).
