I always wondered where the verb "claudicar" in portuguese came from. It means "to limp" and several etymological explanations on the internet claim it comes from the latin "claudus" meaning "lame". These same websites also claim that the name "Claudius" comes from the same origin. Is it a coincidence that emperor Claudius was actually limp, or was he named because of his infirmity?
His full name was Tiberius Claudius Caesar Augustus Germanicus. Interestingly, he is the only one of the Julio-Claudians who is not referred to by his praenomen (first name, in this case "Tiberius"). He was of the gens Claudia, or Claudian line, which was a very old and distinguished Roman aristocratic family.
