What is the meaning of the name Isaia ?

The baby name Isaia is a Male name , 4 syllables long and is pronounced Italian: ee-ZAH-yah (IPA: /iˈza.ja/),English approximation: eye-ZAY-uh (IPA: /aɪˈzeɪ.ə/).

Isaia is Hebrew, Portuguese, Spanish in Origin.

Isaia is the Italian and Romanian form of the biblical name Isaiah, ultimately from Hebrew Yĕša‘yāh(u), “Yahweh is salvation” or “the Lord is salvation.” The name traveled into Europe through Greek Esaias and Latin Isaias, yielding Romance forms with a final -a. In Italian sources it may appear as Isaìa to mark stress. The eighth‑century BCE prophet Isaiah anchors the name’s significance across Jewish, Christian, and Islamic traditions, and Isaia occurs in Italy both as a given name and a surname; missionary influence also introduced it to Samoan and Tongan usage.

Common variants include Isaiah (English), Isaias/Isaías (Spanish/Portuguese), Isaïe (French), Esaias (Greek, also archaic English and Scandinavian), Jesaja (German/Scandinavian), Izajasz (Polish), and Ézsaiás (Hungarian). Short forms such as Isa and Sai appear in modern use. The enduring appeal of Isaia rests on its concise, uplifting meaning and deep scriptural resonance.
