Could this mean Teacher as well?

[Paulenrique]

Not in Portuguese. In Spanish maestro also means teacher, but in Portuguese is someone who conducts an orchestra.

Oops! Obrigado por isso, irmão! :)

[pietvo]

That would be "mestre", I think.

[Danmoller]

Yes.

Literally, "mestre" is "master".

But sometimes it is used to refer to a teacher.

[PabloA1]

I heard "eu sou maestro", would that be ok?

[Paulenrique]

That means "I am a maestro".

[Danmoller]

It's normal to merge vowels in Portuguese.

Something like "sowo" is "sou o".
Something like "so" is "sou".

Maestro is a word in English?

[pietvo]

Yes, for a conductor or composer, or sometimes someone who masters another art.

[Lahure]

You could use 'I am the conductor' here.

Conductor in English is also used for the person on a train/tram//bus who sells and/or collects the tickets (cue the Marx Brothers). Is there an equivalent in Portuguese?

[deactivated user]

If you mean a ticket inspector on a train = o revisor OU a revisora

[stolijoed]

I used teacher and got dinged as well. I guess it works in Spanish and I think also in Italian at least in the master/apprentice relationship.

[Paulenrique]

Yes, in Portuguese, "Maestro" is not used for teacher.

[Marbeto1]

Conductor is not used in English. Maestro or Director of orchestra are the only ones I`ve used / heard.
