Learn Portuguese (Portugal): Onde está a encomenda? Não ma deste! - Where is the parcel? You did not give it to me!

ma is a contraction of two pronouns: the indirect object me (to me) and the direct object a (it). We use a because "it" refers back to a encomenda, which is a feminine noun. Instead of saying me a, European Portuguese squishes them together into ma.

Why does ma come before the verb instead of after it with a hyphen?

Normally, pronouns attach to the end of the verb in European Portuguese. But the negative word não acts like a magnet, pulling the pronoun in front of the verb. If the sentence was positive, it would go back to the end: Deste-ma! (You gave it to me!).

Which verb is deste?

deste is the simple past tense of the verb dar (to give). Specifically, it is the informal "you" (tu) form. The literal translation of the second half is "Not to-me-it gave-you!"

Does encomenda mean "parcel" or "order"?

It can mean both! a encomenda is very commonly used for a physical package or parcel you receive in the mail, but it is also the noun for an "order" (like goods you requested, matching the verb encomendar, which means to order).
