We say Wednesday as 'quarta-feira' or 'quarta' for short. Quarta means fourth, that is, Wednesday is the fourth day in a week. And so on to the remaining days in a week, except for Saturday ( Sábado) and Sunday (Domingo). In addition, all the days in Portuguese are feminine nouns, except Sábado and Domingo that are masculine ones. Then, we say 'a quarta-feira', 'a segunda-feira' and so on and 'o sábado' and 'o domingo'.
