 The names for these classes stem from the names of the prefixes for 1st and 2nd person singular.The "areal" conjugation is used to convey that the participant is actively involved, whereas the "chendal" conjugation is used to convey that the participant is the undergoer.Note that intransitive verbs can take either conjugation, transitive verbs normally take "areal", but can take "chendal" for habitual readings.
