No Gender Change

❌ Common Pitfalls
Using 'Ser' instead of 'Haber'
Mistake: "Yo soy fallado."

Frequently Asked Questions
What is the difference between 'fallado' and 'fallando'?
'Fallado' is the past participle (the '-ed' form), used to talk about actions that are finished (e.g., 'I have failed'). 'Fallando' is the gerund (the '-ing' form), used to talk about actions happening right now (e.g., 'is failing').
Does 'fallado' always mean 'to fail'?
Not always! While 'to fail' or 'to break down' are the most common meanings, in legal contexts, *fallar* means 'to rule' or 'to give a verdict,' so 'fallado' can mean 'ruled' or 'adjudicated'.
