Frequently Asked Questions
Why do I almost always need 'en' with 'fijarse'?
Think of 'fijarse en' as a single unit that means 'to pay attention *to*' or 'to notice'. The 'en' is like the 'to' or 'on' in English. It connects the action of noticing with the thing you are noticing.
Is 'fijarse' the same as 'notar'?
They are very close synonyms and often interchangeable! 'Notar' (to notice) is a great alternative. 'Fijarse en' often implies a bit more active attention or looking for detail, while 'notar' can be more passive, like simply perceiving something without trying.
