Yiannoula

Yiannoula is a Greek diminutive form of the name Ioanna, which is the Greek equivalent of Joanna or Jane. The name Ioanna itself is derived from the Hebrew name Yochanan (יוֹחָנָן), meaning 'Yahweh is gracious' or 'God is gracious'. This Hebrew name has a long and significant history, appearing in the Old Testament as the name of several figures, most notably John the Baptist in the New Testament.

Over centuries, as Christianity spread, the name Yochanan, through its Greek form Ioannes (for males) and Ioanna (for females), became extremely popular across Europe. The diminutive suffix '-oula' in Greek is often used to convey affection, smallness, or familiarity, making Yiannoula a tender and endearing form of Ioanna, specifically used within Greek-speaking cultures.
