The only marker that cannot occur immediately adjacent to the verb is the secondary marker /kan/, which occurs in a leftward position.
/kan/ is considered a secondary marker, since it is not cliticized like /bi/ and /ge/. At the same time, it only adds a temporal meaning to TAM values already expressed by bare verbs and primary markers.
