Learn how to clarify with "o sea" and "es decir" in Spanish
When we want to introduce an extra explanation, clarification or a consequence of something that has just been mentioned previously, we can use the expression "o sea" or "es decir" then add the explanation/clarification/consequence.
Using one or the other will depend on the formality or informality of the sentence and the context.
O sea (more colloquial)
For example:
Mañana es lunes, o sea, tengo que volver a la rutina.Tomorrow is Monday, in other words, I have to go back to my routine.
Es decir (more formal)
For example
Estudiaremos las civilizaciones precolombinas, es decir, antes de la llegada de Colón.We'll study the prehispanic civilisations, i.e, before the arrival of Columbus.
Both o sea and es decir are invariable expressions, i.e they do not change. It is also important to note that they must always be written as two words, not joined together.
This is incorrect:
- osea
- esdecir
Note that you may sometimes see o sea at the beginning of a sentence, not being used with the function described above.
In this case it is set expression in colloquial Spanish, used to start a sentence with no specific meaning. It is the equivalent to the word "So..." in English, when starting a sentence.
