The Klingon dictionary is clear that numbers "may stand alone as subjects or objects or they may modify another noun." It is an easy logical leap to treat {'ar} in the same way, but {'ar} is not a type of number and so that may not be allowed. TKD says only that {'ar} "follows the noun to which it refers." Does anyone know if any canon which uses {'ar} as a stand alone subject or object? What do you think of that use of it and particularly if teaching that use of it?
