Alphons (Latinized Alphonsus, Adelphonsus, Adefonsus) is a male given name recorded from the 8th century ( Alfonso I of Asturias, r. 739-757) in the Christian successor states of the Visigothic kingdom in the Iberian peninsula. In the later medieval period it became a standard name in the Hispanic and Portuguese royal families.
It is derived from a Gothic name, or a conflation of several Gothic names; from *Aþalfuns, composed of the elements aþal "noble" and funs "eager, brave, ready", and perhaps influenced by names such as *Alafuns, *Adefuns and * Hildefuns. It is recorded as Adefonsus in the 9th and 10th century, and as Adelfonsus, Adelphonsus in the 10th to 11th. The reduced form Alfonso is recorded in the late 9th century, and the Portuguese form Afonso from the early 11th.
Variants of the name include: Alfonso (Spanish and Italian), Alfons (Dutch, German, Catalan, Polish and Scandinavian), Afonso ( Portuguese), Alphonse, Alfonse (Italian, French and English), etc.
