The short answer

Ficar de olho means to keep an eye on, watch, or pay attention to something. It can describe watching an object for a short time, monitoring a message or schedule, or keeping track of a situation. The usual pattern is ficar de olho em.

Use ficar de olho for attention or monitoring

The expression is informal and does not automatically imply suspicion. The context tells you whether someone is watching a bag, checking for an update, or noticing a change.

Can you keep an eye on my backpack?

Conjugate ficar and contract em with the noun

Conjugate ficar to match the subject and tense: fico de olho (I keep an eye out), ficou de olho (he or she kept watch), and vamos ficar de olho (we will keep an eye on it). The phrase de olho remains the same.

The preposition em contracts with a definite article: em + a becomes na, em + o becomes no, and em + as/os becomes nas/nos. That is why you say ficar de olho na porta but ficar de olho em uma porta.

Ela ficou de olho nos preços durante a semana.

She watched the prices during the week.

I keep an eye out for a new opening.

Put it into practice

Use ficar de olho em for watching or monitoring something; conjugate ficar and contract em with a definite article when needed.
