Questions & Answers about A chave da senhora está na mesa.

Why is da senhora used instead of a possessive like sua?

Portuguese often shows possession with de + the owner:

• a chave da senhora = the lady’s key / your key (depending on context)

This is very common and often clearer than sua chave, because sua can be ambiguous in Portuguese. It might mean:

• your
• her
• sometimes even his, depending on context

So da senhora is a more explicit way to say who the key belongs to.

What exactly is da?

Da is a contraction of:

• de = of
• a = the

So:

• de + a = da

In a chave da senhora, da senhora literally means of the lady.

This kind of contraction is extremely common in Portuguese.

Why is there an article before senhora?

Portuguese uses definite articles much more often than English does.

So where English might say:

• the lady’s key

Portuguese says:

• a chave da senhora

That a inside da comes from the article that goes with senhora.

In Portuguese, nouns like senhora often appear with an article, especially in structures like possession.
