Origins

Traditionally said to be from claudus (“lame, limping, crippled”), however, family history relates that the name was adopted as the Romanized form of an earlier Clausus, the Latin spelling of an original Sabine name. A Sabine word cognate with clausus (“shut, closed”), perfect passive participle of claudō (“to shut, close”) seems a more probable origin.
