Yannos / Ioannis / Giannis / Yiannis / John / Juan / Jean

Yannos is a Greek diminutive or variant of the name Ioannis, which is the Greek form of John. The name John itself originates from the Hebrew name Yochanan, meaning 'Yahweh is gracious' or 'God is gracious'. Over centuries, as Christianity spread, the name Ioannis became extremely popular in Greece and other Orthodox Christian countries. Yannos emerged as a common affectionate or informal form of Ioannis, much like 'Johnny' is to 'John' in English-speaking cultures.

The name has deep roots in Christian tradition, primarily due to John the Baptist and John the Apostle. In Greece, names derived from Ioannis are ubiquitous, and Yannos maintains a friendly, approachable feel while still carrying the weight of its ancient and religious heritage. It is often used as a standalone name today, though its connection to Ioannis remains strong.
