The original diphthong was lost in Dutch Hendrik (hypocoristics Henk, Hennie, Rik) and Scandinavian Henrik[9] (whence Henning).

Herry was adopted into Welsh as Perry; into Irish as Annraoi, Anraí, and Einrí; and into Scottish Gaelic as Eanraig, Eanruig.

In Southern Europe, variants without the initial "H" include Italian Arrigo, Enrico, and Enzo; Catalan language and Occitan Enric; and Spanish Enrique (whence Basque Endika).

Emmerich is the origin of a separate suite of variant names used across Western and Central Europe, although these never rose to the ubiquity of the variants of Henry: English Emery, Amery, Emory; French Émeric, Aymeric; Hungarian Imre, Imrus; Slovak Imrich; Italian Amerigo; and Iberian (Portuguese, Spanish, Galician) Américo.
