The story
- Middle English · inherited fromJesu
- English todayJesu
From Middle English Jesu, from the vocative (and genitive, etc) form Jēsū of Latin Jēsūs, and also reflective of the vocative (and genitive, etc) form Ἰησοῦ (Iēsoû) of Ancient Greek Ἰησοῦς (Iēsoûs). Gradually displaced as the normal form by Jesus in the Middle English and Early Modern English period, but retained or restored especially in a few religious texts on the model of Latin and Greek.
