Questions & Answers about Naskiĝatesto estas la bazo de la peto.

Why is naskiĝatesto written as one word?

Esperanto very often builds new nouns by combining roots into a single compound word.

• naskiĝ- = birth
• atest- = attest, certify
• -o = noun ending

So naskiĝatesto literally means something like birth-certificate or birth attestation.

This kind of compounding is extremely common in Esperanto, and it often feels more natural than using several separate words.

What is the role of -o in naskiĝatesto, bazo, and peto?

The ending -o marks a noun in Esperanto.

So:

• naskiĝatesto = a birth certificate
• bazo = base, basis
• peto = request, application, petition

This is one of the most regular parts of Esperanto grammar: if you see -o, you are usually looking at a noun.

Why does the sentence use estas?

Estas is the present-tense form of esti, meaning to be.

So:

• estas = is / are / am

In this sentence, it links the subject and the description:

• Naskiĝatesto = subject
• estas = is
• la bazo de la peto = the basis of the request

So the structure is simply: X is Y.
