The name is most commonly derived from the عيسى ‘Isa, an Arabic translation of Jesus, itself having a Hebrew origin. However, it is not the only translation; it is most commonly associated with Jesus as depicted in Islam, and thus, commonly used by Muslims. Meanwhile, Arabic-speaking Christians would use يسوع Yasū‘, a more phonetic translation of Jesus. The origin of the Quranic Isa is complex and is detailed below.
Isa was also used in the Frisian (Old Germanic) language for both males and females and was a short form of Germanic names beginning with the element "is", meaning ice and iron.
The English form of the name "Jesus" is derived from the Latin Iēsus, which in turn comes from the Greek Ἰησοῦς (Iēsoûs). The Greek is a Hellenized form of the Hebrew name Yēšua (ישוע), which is in turn a shortened form of Hebrew Yehōšua (יהושע) or "Joshua" in English. Aramaic (Classical Syriac) and East Syriac, which are ancestral to West Syriac, render the pronunciation of the same letters as ܝܫܘܥ ishoʕ (išoʕ) /iʃoʕ/. The Aramaic Bible (c. 200 AD) or the Peshitta preserve this same spelling. The Encyclopedia of the Qur'an by Brill Publishers quotes scholarship that notes that the Greek name Iesous, Ἰησοῦς (Iēsoûs), also is known to have represented many different Biblical Hebrew names (which causes issues when seeking to find what Jesus' original Hebrew name would have been from the Greek) "Josephus used the Greek name lesous to denote three people mentioned in the Bible whose Hebrew names were not Yeshua', Y'hoshua' or Y'hoshua'. They were Saul's son Yishwi (Anglicized as 'Ishvi' in the RSV of I Samuel 14:49), the Levhe AbTshua' (mentioned in I Chronicles 6:4, etc.) and Yishwah the son of Asher (Anglicized as 'Ishva' in the RSV of Genesis 46:17). ... Josephus furnishes important evidence for the wide variety of Hebrew names represented in Greek by Iesous"
Also, the classical theologians Clement of Alexandria and Cyril of Jerusalem both stated that the Greek name Iesous was allegedly Jesus' original name itself and that the name was not a transliteration of a Hebrew form.
There is a major discrepancy between the Hebrew/Aramaic and Muslim Arabic forms of this name, since the Hebrew form of this name has the voiced pharyngeal ʿAyin ע or ʿAyn ع consonant at the end of the name (as does Christian Arabic يسوع yasūʿ), while the Muslim Arabic form عيسى `īsā has the `Ayn at the beginning of the name. For this reason, some (such as Ahmed Deedat) state the Arabic name Isa is related to the Biblical name Esau (which begins with a pharyngeal); it is also similar in the vowels to an Aramaic version of Jesus, viz. Eeshoʿ (Aramaic forms of the name, however, still have the voiced pharyngeal `Ayn consonant at the end of the name). and Arabic ʕiisa
