Questions & Answers about La araba nomo aperas sur la mapo.

Why is it araba nomo and not arabo nomo?

Because araba is an adjective, and adjectives in Esperanto end in -a.

• araba = Arabic, Arab
• nomo = name

So la araba nomo means the Arabic name.

By contrast, arabo with -o is a noun meaning an Arab person.

So:

• araba nomo = an Arabic name
• arabo = an Arab

What do the endings -o and -a mean here?

These are basic Esperanto word-class endings:

• -o = noun
• -a = adjective

So in this sentence:

• nomo = name
• mapo = map
• araba = Arabic

This system is very regular in Esperanto, and learners usually rely on these endings a lot.

Why does araba have the same ending style as an adjective? Does it have to agree with nomo?
