This is the 30th most frequent Portuguese word.
aos
The Portuguese word "aos" means "to the" or "to" (used with plural masculine nouns).
Here, 'aos' combines the preposition 'a' (to) with the article 'os' (the), forming a contraction meaning 'to the' when referring to a masculine plural noun.
Eu entreguei os documentos aos advogados.
I handed over the documents to the lawyers.
In this instance, 'aos' is used similarly to the previous example, contracting 'a' with 'os' (to the participants).
Os agradecimentos foram dirigidos aos participantes.
The thanks were addressed to the participants.
In this case, 'aos' functions in the same way, indicating 'to the' in the phrase 'to the details' and showing its utility in a phrase where it pairs with a plural masculine noun.
