Frequently Asked Questions
Why is 'antecedentes' always plural?
Spanish treats 'antecedentes' as a collection of previous events or facts, not a single item. Think of it like the English word 'data' or 'information'—even though we might think of it as one thing, the Spanish structure requires the plural form.
How do I ask someone about their background without sounding like a police officer?
If you mean general background (like family or education), it's better to use phrases like '¿Cuál es tu formación?' (What is your education/training?) or '¿De dónde vienes?' (Where are you from?). 'Antecedentes' is often too formal or suggests a legal inquiry.
