Learn Portuguese (Portugal): Temos orgulho no nosso trabalho.

In English, we use the verb to be plus an adjective (we are proud). In Portuguese, you express this by using the verb ter (to have) plus the noun orgulho (pride). You are literally saying: We have pride.

Why does the sentence use no when the English translation says of?

In English, we are proud of something, but in Portuguese, you have pride in something. The word orgulho is followed by the preposition em (in). Here, em combines with the masculine singular article o to become no.

Why is there a definite article (the o hidden inside no) before nosso trabalho?

In European Portuguese, possessive words like nosso (our) almost always need a definite article like o (the) in front of them. So instead of just saying em nosso trabalho, the preposition em merges with the article o to create no nosso trabalho (literally: in the our work).
