How to Say "to spot" in Spanish
The most common Spanish word for “to spot” is “detectar” — use 'detectar' when you mean to find or notice something concrete, like an error, a signal, or a physical object, often with the help of a tool or keen observation..

Using 'A' with People
When you detect a person (like a thief), you must put the word 'a' before them: 'Detectaron a un intruso'. If it's an object, like a sound, you don't need it: 'Detectaron un ruido'.
A Friendly Regular Verb
This verb is completely regular! It follows the exact same pattern as 'hablar' or 'cantar' in all its forms.
Detectar vs. Sentir
Mistake: “Detecto cansancio.”
Correction: Siento cansancio. Use 'detectar' for external things you discover, but 'sentir' for internal feelings or physical sensations you have yourself.
