*En or *Enji (ɛɲi) is a reconstructed name of the fire god in the Albanian pagan mythology, which has continued to be used in the Albanian language to refer to Thursday (e enjte).
The deity to whom Thursday was dedicated in Albanian is considered to have been worshiped by the Illyrians in antiquity and he may have been the most prominent god of the Albanian pantheon in Roman times by interpreting Jupiter, when week-day names were formed in the Albanian language. The belief in a prominent fire god, who was referred to as I Verbti ("the blind one"), and who was often regarded more powerful than the Christian God, survived in northern Albania until recent times. Under Christianization the god of fire was demonized and considered a false god, and it was spread about that anyone who invoked him would be blinded by fire.
In Albanian tradition the divinised fire is regarded as the Sun's offspring (pjella e Diellit), which is symbolized by the fire hearth (vatra e zjarrit).
The root of the name of the Albanian deity is thought to be found in antiquity in the Pannonian-Illyrian area, as well as in Messapia/Iapygia in southern Italy such as Ennius, interpreted as a theophoric name: "the one dedicated to En". Other examples with the same root and with the suffix -c (-k) are Enica, Enicus, Enicenius, and with the suffix -n are Eninna, Ennenia, and the short forms Enna and Enno. Compounds of the divine name En are Enoclia "En, the famous", and Malennius containing the Albanian term mal "mountain", interpreted as "the one dedicated to En of/from the mountain".
In his work Speculum Confessionis (1621) Pjetër Budi recorded the Albanian term tegnietenee madhe for the observance of Maundy Thursday (S.C., 148, vv. 26, 89). In his Latin-Albanian dictionary (Dictionarium latino-epiroticum, 1635), Frang Bardhi recorded dita ehegnete as the Albanian translation of Latin dies Iovis. In 1820, the French scholar François Pouqueville recorded two old Albanian terms: e igniete and e en-gnitia.
