A suffix that is used in some examples for agental-formation: creating nouns from verbs that indicate the agent who performs the verb’s action. The clearest example is sapthân “wise man” derived (after some ancient sound modifications) from saphad- “to understand”. This formation means “*one who understands”. Less clear examples are magân “wright, builder”, perhaps from a verb mag- “to build”, and kathuphazgân “conquerer”, perhaps a combined of katha “all” and a verb ?phazag- “to take”, meaning “one who takes all”.
It is not clear how this suffix related to the similar participle suffix -ân used for form adjectives from verbs. See the entry on participle for further discussion. Andreas Moehn suggested (EotAL/TAN) that -ân as an agental formation may be related to anâ “human being”.
