Fadeyka is an East Slavic affectionate diminutive of Fadey/Fadei (Фадей), the Russian and Ukrainian form of Thaddeus. The name came into Slavic use via Church Slavonic from Greek Thaddaios, ultimately from Aramaic Taddai, often interpreted as “heart” or “courageous-hearted.” Because of its link to the Apostle Jude Thaddeus, it appears in Orthodox calendars, and the diminutive Fadeyka occurs in 18th–19th‑century parish and census records in Russia and Ukraine as a familiar call name for boys and men named Fadey.

Variants and related forms include Fadey, Fadei, Faddey (older transliteration) and the Ukrainian pet form Fadeyko; cognates abroad are Thaddeus (English), Thaddée (French), Tadeo (Spanish), Taddeo (Italian), Tadeusz (Polish), Tadeáš (Czech), and Tadej (Slovene/Slovenian). While Fadeyka remains rare as a formal given name today, it can be chosen as a charming, old‑world nickname or as an unconventional independent choice with a warm, brave-hearted meaning.
