 The marker "ta-" is always used with the irrealis mood, therefore falling after the irrealis marker "‘a-," as in (2), to mark situations which were expected to occur, but have not.The form "ta-" also commonly occurs with the eventuality marker we-, as seen in (2), resulting in "tawe".This is used to refer to events that have not happened yet, and "ta-" alone simply refers to those that have not happened.
