John (given name)

In the Roman sphere of influence, Johannes became the Italian Giovanni (also Gianni, Gian and other derivatives). In the Black Sea region, the name became the Romanian Ioan and Ion. In Iberia the name eventually changed to the Spanish Juan, feminine Juana; in the medieval Portuguese it was Juo / Joane / Joan, now João (pronounced [ʒuˈʌ̃ũ]), feminine Joana, and also Ivo; in Galician, the orthography is Xan or Xoán, feminine Xoana. In Gaul, it became the Old French Jehan (the 16th century John Calvin still spelled his name Jehan Cauvin) and later Jean (pronounced [ʒɑ̃]); the female form was Jehanne (the 15th century Joan of Arc still spelled her name Jehanne) and later Jeanne. In the Occitano-Romance area, it became Joan (feminine, Joana) and Jan in Occitan and Catalan, from older Iouan and Iohan. In Ladin, it became Giuani.

In Moldavia and Wallachia, the name became a title abbreviated as Io used mainly by the royalty.

The Germanic languages (including German, English and Scandinavian) produced the masculine Johann (also Johan (Dutch)), Joan,[5] Jan and Janke (Dutch), Jannis, Jens (Danish and Frisian), Jóhannes, Jóhann, (Icelandic and Faroese), Jön (Swedish), Hans (German, Dutch and Scandinavian)[6][7] and the feminine Johanna (also the Dutch diminutives Johanneke, Hanneke, Janneke, and Joke). In England, the name John came from the Anglo-French language form Johan, itself from the Old French form Jehan. Prior to the standardization in English of the letter 'J', the letter 'I' was used interchangeably; following this shift, forms beginning in J- such as John began to be pronounced in their modern fashion with <dʒ> rather than <j> (y). Seventeenth-century English texts still spelled the name Iohn. Since then, it has been spelled in its current form, John. The feminine form changed from Jehanne to Joanne, Joan and Jo.

In Welsh, the name John is rendered as Ieuan (pronounced [ˈjəɨ̯an]), Ifan (pronounced [ˈɪvan]), Iwan (pronounced [ˈɪu̯an]), Ioan (pronounced [ˈjoːan]) or, borrowed from English, Siôn (pronounced [ˈʃoːn]). A pet form is Ianto (pronounced [ˈjantɔ]). Ifan eventually became rendered into English as Evan. In Irish, it is written as (pronounced [ˈoːənˠ]), Eóin, (pronounced [ˈoːənʲ]) or Seán (pronounced [ˈʃɑːn]). The last is a Gaelicisation of the Norman–French 'Jean'. In some cases, the pronunciation of the original initial "Y"/"I" also changed to variants of "J". In Scotland, it is Iain or Ian. In Cornish (archaically; Jowan/Iowan) and Devon dialects, the form Jan gives rise to the nickname of Plymothians as 'Janners' and the midsummer festival of St. John, Golowan. The Breton form of this name is Yann, the Manx is Juan, and the Cornish is Yowann.

In Hungarian, Johannes became János, and in the Slavic languages Ivan, Jan, Ján, Honza, Janez and Jovan. In Albanian, Gjoni , Xhon, Xhoni and Jovan is used for males.

Henna (Arabic: حنّا‎) is a common Arabic translation of John as are Yūḥannā (Arabic: يُوحَنّا‎) and Yaḥyā (Arabic: يحيى‎). All are common Arabic male given names. And because Yahyā/John the Baptist is a prophet in Islam, Yahya is a very common name among Muslims.
