"They see us."

Translation: Eles nos veem.

[deactivated user]

A verb book I have gives "vêem". Is the accent mark now obsolete?

[Paulenrique]

Yes, it is no longer used when you have the same vowels together... veem, leem, creem, etc

[andreaparker]

Would the pronoun [nos] be in the same position in the sentence in European Portuguese?

[erudis]

In European Portuguese you'll probably hear "Elas veem-nos.".

[TiagoMoita_PT]

Yes. Not probably, it's the only accepted form. At least in the Present Tense. If it were the Subjunctive, the pronoun comes before the verb (se / que / quando NOS vissem / vejam / virem). Mind the accent, by the way.

[reno300]

In Brazil can we also say "Elas veem nos" and still be understood?

[magicbeans]

You'll be understood, but it'll sound very weird, and it's not correct. "Elas nos veem" would sound too formal too. You'll most likely hear "elas veem a gente", actually.

[KTKee-EnglishEng]

I think most people learn languages to speak and listen, so teaching these arcane forms is wrong and pointless I think.
