Evanthia is a Greek feminine given name derived from the Greek word 'евангелие' (evangelion), which translates to "good news" or "gospel". It was traditionally used by Eastern Orthodox Christians, especially in Greece and other Hellenic communities, as a name for girls born around Eastertime. The name Evanthia is composed of two elements: 'ευ' (eu), meaning "good", and 'ανθοσ' (anthos), translating to "flower". Therefore, the name Evanthia can be interpreted as "good flower" or "blossom". It was particularly popular during the 19th century in Greece but has since become less common. Despite its decreasing usage, Evanthia remains a part of Greek onomastic tradition and is still encountered among the older generations in Greece and the diaspora.
"The name Evanthia experienced a resurgence in popularity from the late 1970s to the early 2000s, with peaks in 1977, 1982-1984, and 2001-2005. However, it seems to have fallen out of favor again recently, with only five births each in 2023 and 2021."
