The Unique Pattern of Portuguese Weekday Names

Unlike most other Romance languages, Portuguese weekday names (except for Saturday and Sunday) do not derive from the names of celestial bodies or pagan deities. Instead, they are numbered, a feature that immediately sets them apart. Let’s break down how each day got its name and why Portuguese took this unusual path.

Historical Context: From Pagan Gods to Christian Influence

In Latin and most Romance languages, the days of the week were named after Roman gods and celestial bodies. For example, the French “lundi” (Monday) comes from “Luna” (moon), and the Spanish “miércoles” (Wednesday) comes from “Mercurio” (Mercury). However, in the 6th century, a significant shift occurred in the Iberian Peninsula, particularly within the Christian church.

The Catholic Church sought to distance itself from pagan traditions and emphasize Christian values. This led to a reform by Saint Martin of Braga, a prominent figure in the early church in what is now Portugal. He replaced the pagan-derived names with a numbered system based on the concept of the “Feriae,” which were days of rest or celebration in the Roman tradition, especially observed in Christian liturgy.

The Meaning Behind Each Portuguese Weekday Name

Segunda-feira (Monday)

“Segunda” means “second.” The word “feira” comes from the Latin “feria,” meaning a day of celebration or feast. So, “segunda-feira” translates to “second day of liturgical celebration.” In Christian tradition, Sunday is the first day of the week, making Monday the second.

Terça-feira (Tuesday)

“Terça” means “third.” Thus, “terça-feira” is the third day of the liturgical week.

Quarta-feira (Wednesday)

“Quarta” means “fourth.” “Quarta-feira” is the fourth day, following the same pattern.

Quinta-feira (Thursday)

“Quinta” means “fifth.” Thursday is thus the fifth day in the sequence.

Sexta-feira (Friday)

“Sexta” means “sixth.” “Sexta-feira” is the sixth day of the week.

The Exceptions: Sábado and Domingo

The first and last days of the week retain non-numbered names, reflecting ancient and biblical roots.

Domingo (Sunday)

From the Latin “Dominicus,” meaning “of the Lord,” Sunday is the day dedicated to worship and rest in Christian tradition.

Sábado (Saturday)

Derived from the Hebrew “Shabbat” (Sabbath), “sábado” signifies the day of rest, as observed in Jewish and Christian traditions.

Comparison with Other Romance Languages

While Spanish, French, and Italian weekday names are mostly rooted in Roman gods and celestial bodies (e.g., Spanish “lunes” for the moon, French “mardi” for Mars), Portuguese stands out with its strictly Christian, liturgical naming system. This unique tradition is not found in other major Romance languages, making Portuguese an interesting study for language enthusiasts and learners.

Why This Matters for Portuguese Learners

Understanding the origins of the Portuguese weekdays not only helps you remember their names more easily but also gives you insight into the religious and historical factors that shaped the language. This cultural context is invaluable for anyone striving for fluency and cultural competence.
