Questions & Answers about ¡Buenos días!

Why is it buenos días and not buen día?

In Spain, buenos días is the standard fixed expression for good morning.

A native English speaker often expects a singular noun because English says morning, but Spanish uses the plural días in this greeting. You should learn it as a set phrase.

In Spain, buen día is not the normal greeting. You may hear it in some other Spanish-speaking countries, but buenos días is what you should use for Spain.

Why is it buenos and not buenas?

Because días is a masculine plural noun, the adjective has to agree with it.

• día = masculine
• plural: días
• adjective in masculine plural: buenos

So:

• buenos días
• buenas tardes
• buenas noches

This is a good example of adjective agreement in Spanish.

If día ends in -a, why is it masculine?
