Usage notes

Sometimes is considered simply an alternative spelling and pronunciation of errant', though many authorities distinguish them, reserving '''errant''' to mean “wandering” and using it ''after'' the noun it modifies, notably is “knight '''errant ”, while using ''arrant'' to mean “utter”, in a negative sense, and ''before'' the noun it modifies, notably in “''arrant knaves”. Etymologically, arrant arose as a variant of errant , but the meanings have long since diverged. Both terms are archaic, primarily used in set phrases (which may be considered ), and are easily confused, and on that basis some authorities suggest against using either.
