+! In some verb phrases, the forms that express the Progressive actually take
+! 0-IPFV, rather than yi-PROG, inflection (e.g., Bruce states that the PROG
+! form of tadììtł'á "start to dance" is taatł'ásh "he/she/it is dancing",
+! which inflects like a regular 0-IPFV verb).
+!
+! We represent this overlap by analyzing such forms as serving the role of
