If both the reflexive marker and the causative marker in a language are affixes, both are: (a) either prefixes (cf. Abkhaz, Amharic, Klamath), or (b) suffixes (Yakut, Quechua, Aymara) or (c) the reflexive marker is a prefix and the causative marker is a suffix (Georgian, Ainu, Nivkh, Luganda, Shoshone); it is unlikely for the reflexive marker to be a suffix and the causative marker, a prefix.

IF both reflexive marker and the causative marker are affixes, THEN it is unlikely for the reflexive marker to be a suffix and the causative marker a prefix. The likelihood is that they are both prefixes or both suffixes, or that the reflexive is a prefix and the causative a suffix.
The reciprocal marker (if there is one distinct from reflexive marker) is similar in this respect to the causative marker (Nedjalkov 1980: 227).
