Learn Portuguese (Portugal): Nós queremos comer a sobremesa no jardim. - We want to eat the dessert in the garden.

When you use a modal verb like querer (to want) alongside another action, you only conjugate the first verb. Since queremos is already conjugated to match Nós, the second verb comer (to eat) must stay in its infinitive (base) form.

In English we often just say "eat dessert". Why is there an a before sobremesa?

Portuguese uses definite articles like a (the) much more often than English does. Even when you are talking about eating dessert in a general sense, it is standard practice to include the article, making it comer a sobremesa.

Where does the word no come from in no jardim?

The word no is a mandatory contraction (blending) of the preposition em (in) and the masculine definite article o (the). Because jardim is a masculine noun, saying "in the garden" requires you to merge em and o into no.

Can I drop the word Nós and just start the sentence with Queremos?
