Spanish Days of the Week

The role of Spanish Language in the Current World

Spanish is a major language spoken in 21 countries around the world, spoken by more than 577 million people, according to the Spanish newspaper El País and a report that gathered information from the Cervantes Institute’s published records.

Of those, 480 million people are native speakers of the Spanish language.

The language has taken hold in a number of non-native speaking countries, including the United States. According to Professor David Fernández Vítores of the University of Alcalá, there were 40 million Spanish speakers registered inside the United States of America in 2017.

If the growth tendency continues, in ten years more people will speak Spanish in the United States of America than they do in Spain!

For anyone considering learning a language, Spanish is and will continue among the most valuable in terms of both career and travel advantages.

Days of the Week in Spanish and the Romance Languages

As you may know, Romance languages belong to the Italic line of the Indo-European branch in the language family tree.

Therefore, if you already are a native speaker of French, Romanian or Italian or you have learnt some of these as a second language you will have an advantage over those who haven’t.

Take note of the next comparison table showing the days of the week in five Romance languages: Spanish, French, Italian, Catalan, and Romanian.

The Roman Calendar and the Days in Spanish

There is a striking resemblance between the names for the days of the week in various Romance languages.

This is due to the fact that, during the span of the Roman Empire, the Latin language was spread across the conquered lands.

Vulgar Latin, from which French, Italian, and Spanish were formed, was actually spoken by soldiers, slaves, and common people.

Ancient Romans named the days of the week after the Sun, the Moon, and the five planets that were visible to them when they looked at the sky.

Interestingly enough, Sunday was originally derived from the “Sun’s Day,” although was later changed to the “Lord’s Day” once Christianity took hold.
