Preposition a contractions (ao, à, aos, às)

The Preposition "a"

When talking about going "to" a place for a short visit or errand, we use the preposition a. Because Portuguese places have gender and number, they usually require a definite article ("the").

When the preposition a meets these articles (o, a, os, as), they merge into a single word. Notice that for feminine locations, a grave accent is added to show that the two "a"s have overlapped (à and às).
