Etymology
Adjective
errant (comparative more errant, superlative most errant)
Straying from the proper course or standard, or outside established limits.
Wandering; roving around.
Prone to making errors; misbehaved.
(proscribed) Utter, complete (negative); arrant.
Usage notes
Sometimes arrant (“utter, complete”) is considered simply an alternative spelling and pronunciation of errant, though most authorities distinguish them, reserving errant to mean “wandering” and using it after the noun it modifies, notably in “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 primarily used in set phrases (which may be considered cliché) and, since they are easily confused, some authorities suggest against using either.
