The Greek Iēsous is “only” a proper name but one with great importance. The following quote by John Ellington (in The Bible Translator 1993, p. 401ff.) illustrates this:
“In Matthew’s account of the birth of Jesus Christ, Joseph is told that when Mary gives birth to a son ‘you will name him Jesus, because he will save his people from their sins’ (1:21). This name is a Greek transliteration of the Hebrew name [Yeshua (יֵשׁוּעַ) which is a short form of a name meaning] ‘the Lord [Yahweh] saves.’ The name is very significant and is in itself especially dear to Christians around the world. (…) Unquestionably great importance is attached to the name of Jesus by Christians of all persuasions and backgrounds.”
While Iēsous (pronounced: /i.ɛː.suːs/) is transliterated as “Jesus” (pronounced /ˈdʒiːzəs/) in English it is transliterated and pronounced in a large variety of other ways as well, following the different rules of different languages’ orthographies, writing systems and rules of pronunciation. The following is a (very partial) list of forms of Jesus in Latin characters: Chesús, Ciisusu, Gesù, Gesû, Gesü, Ġesù, Giêsu, Hesu, Hesús, Iesu, Ihu, Íosa, Ìosa, Isus, Isus, Isus, Isuthi, Îtu, Jasus, Jeesus, Jeesus, Jehu, Jeso, Jesús, Jésus, Jesúsu, Jethu, Jezi, Jézi, Ježiš, Jezus, Jézus, Jėzus, Jēzus, Jezusi, Jėzus, Jezuz, Jisos, Jisọs, Jisas, Jisu, Sisa, uJesu, ŵaYesu, Xesosi, ´Xesús, Ya:su, Yecu, Yēēsu, Yeso, Yésʉs, Yexus, Yezo, Yezu, Yiisu, Yiitju, Yisufa, Yusu, Zîsɛ, Zjezus, and this (equally incomplete) list with other writings systems: ᔩᓱᓯ, Յիսուս, ᏥᏌ, ኢየሱስ, ܝܫܘܥ, Ісус, 耶稣, იესო, ईसा, イエス, 예수, येशू, യേശു, ජේසුස්, যীশু, ‘ঈছা, இயேசு, ఏసు, เยซู, យេស៊ូ, يَسُوعَ (note that some of these might not display correctly if your computer does not have the correct fonts installed).

In some languages the different confessions have selected different transliterations, such as in Belarusian with Isus (Ісус) by the Orthodox and Protestant churches and Yezus (Езус) by the Catholic church, Japanese with Iesu (イエス) (Protestant and Catholic) and Iisusu (イイスス) (Orthodox), or Lingala with Yesu (Protestant) or Yezu (Catholic). These differences have come to the forefront especially during the work on interconfessional translations such as one in Lingala where “many hours were spent on a single letter difference” (source: Ellington, p. 401).
In Chinese where transliterations of proper names between the Catholic and Protestant versions typically differ vastly, the Chinese name of Jesus (Yēsū 耶稣) remarkably was never brought into question between and by those two confessions, likely due to its ingenious choice.

The proper name of God in the Old Testament, Yahweh (YHWH), is rendered in most Chinese Bible translations as Yēhéhuá 耶和華 — Jehovah. According to Chinese naming conventions, Yēhéhuá could be interpreted as Yē Héhuá, in which Yē would be the family name and Héhuá — “harmonic and radiant” — the given name. In the same manner, Yē 耶 would be the family name of Jesus and Sū 稣 would be his given name. Because in China the children inherit the family name from the father, the sonship of Jesus to God the Father, Jehovah, would be illustrated through this. Though this line of argumentation sounds theologically unsound, it is indeed used effectively in the Chinese church (see Wright 1953, p. 298).
Moreover, the “given name” of Sū 稣 carries the meaning ‘to revive, to rise again’ and seems to point to the resurrected Jesus. (Source: J. Zetzsche in Malek 2002, p. 141ff., see also tetragrammaton (YHWH))
There are different ways that Bible translators have chosen historically and today in how to translate the name of Jesus in predominantly Muslim areas: with a form of the Arabic Isa (عيسى) (which is used for “Jesus” in the Qur’an), the Greek Iēsous, or, like major 20th century Bible translations into Standard Arabic, the Aramaic Yēšūaʿ: Yasua (يَسُوعَ). (Click or tap here to see more.)
Following are languages and language groups that use a form of Isa include the following (note that this list is not complete):
- Indo-Iranian languages: Persian, Dari, Central Pashto, Southern Pashto all use Eysa (عيسی or عيسىٰ for Southern Pashto), Sindhi uses Eysey (عيسيٰ), Southern Balochi Issa (ایسّا), Central Kurdish (Sorani) and Northern Kurdish (Kurmanji) use Îsa (عیسای and Иса respectively), Turkmen has Isa, and Tajik Isoi (Исои — compare Iso/Исо in the Tajik Qur’an)
- Turkic languages: Turkish uses İsa, Kazakh, Kumyk, Nogai, Crimean Tatar all have Isa (Иса), Kirghiz has Iysa (Ыйса), Uzbek has Iso (Исо — compare Iiso/Ийсо in the Uzbek Qur’an), Bashkir uses Aaisa (Ғайса), North Azerbaijani İsa, Uighur uses Eysa (ئەيسا), and Kara-Kalpak İysa (Ийса)
- Caucasian languages: Bezhta and Lezghian use Isa (Иса), Avaric has Aisa (ГІиса), and Chechen Iza (Иза)
- Various African languages: Somali, a Cushitic language, has Ciise, Kabyle has Ɛisa and Tahaggart Tamahaq has Yeswa (both Berber languages), the Saharan languages Central Kanuri, Manga Kanuri have Isa, the Atlantic-Congo languages Dagbani, Mampruli, and Bimoba use Yisa, and the Chadian Arabic Bible has Isa (عِيسَى)
- Some languages have additional “TAZI” editions (TAZI stands for “Tawrat, Anbiya, Zabur, and Injil” the “Torah, Prophets, Psalms and Gospel”) of the New Testament that are geared towards Muslim readers where there is also a translation in the same language for non-Muslims. In those editions, Isa is typically used as well (for example, the Khmer TAZI edition uses Isa (អ៊ីសា) rather than the commonly used Yesaou (យេស៊ូ), the Thai edition uses Isa (อีซา) rather than Yesu (เยซู), and the English edition also has Isa rather than Jesus.)
In German the name Jesus (pronounced: /ˈjeːzʊs/) is distinguished by its grammatical forms. Into the 20th century the grammatical rules prescribed a unique Greek-Latin declination: Jesus (nominative), Jesu (genitive, dative, vocative), Jesum (accusative), from which today only the genitive case “Jesu” is still in active use.
In Lamba the name ŵaYesu consists of a transliteration Yesu and the prefix ŵa, a plural form for “proper names when addressing and referring to persons in any position of seniority or honor.” While this was avoided in early translations to avoid possible misunderstandings of more than one Jesus, once the church was established it was felt that it was both “safe” and respectful to use the honorific (plural) prefix.
