Spanish Phrase
¿Cuándo empezó el problema?
Meaning
This question asks for the exact moment a problem began. The preterite 'empezó' signals a completed start point, so the speaker expects a specific time reference (e.g., 'ayer', 'a las tres').
When to use
Use this phrase when troubleshooting, discussing a recent issue at work, school, or in daily life, and you need to pinpoint when the trouble first appeared.

✕Common Mistakes
¿Cuando empezó el problema?
Missing accent changes the word to the conjunction 'cuando' (meaning 'when' in statements), which is incorrect in a question.
¿Cuándo empezaba el problema?
Imperfect 'empezaba' suggests an ongoing or repeated start, not a single point in time; use preterite 'empezó' for a specific moment.
¿Cuándo empezó un problema?
Using the indefinite article changes the nuance; the question usually refers to a known issue, so 'el problema' is preferred.
↔Alternatives

¿A qué hora comenzó el problema?

Cultural Tip
In Spanish, the preterite is preferred for a concrete start time, while the imperfect (empezaba) would imply an ongoing or repeated beginning. Also, remember to open and close the question with inverted and regular question marks – a hallmark of written Spanish that learners often forget.
