⚠️ Common Mistakes

If you are the one feeling the fear, you need the reflexive pronoun 'me'. 'Yo asusto' means 'I scare (other people)', which is probably not what you mean!
El perro grande se asustó al cartero.
El perro grande asustó al cartero.
The dog is doing the scaring, not feeling it. Since the action is directed at someone else (the mail carrier), you use the non-reflexive form 'asustó'.

Frequently Asked Questions
Is this '-se' thing common with other verbs?
Yes, absolutely! This is a reflexive verb. Many Spanish verbs work this way, where the '-se' ending shows the action is happening to the person doing it. For example, 'enojar' is 'to anger someone', but 'enojarse' is 'to get angry'.
Can 'asustar' and 'asustarse' be used in the same sentence?
Yes, they can. For example: 'Mi hermano me asustó y yo me asusté mucho' (My brother scared me and I got very scared). This shows the cause (he scared me) and the effect (I got scared) perfectly.
