Charles Darwin's discovery explained something.
In the form Charles, the initial spelling ch- corresponds to the palatalization of the Latin group ca- to [ta] in Central Old French (Francien) and the final -s to the former subjective case (cas sujet) of masculine names in Old French like in Giles or James (< Latin -us, see Spanish/ Portuguese Carlos)
== History ===== Early Middle Ages ===The name is atypical for Germanic names as it is not composed of two elements, but simply a noun meaning "(free) man"
