There's a very interesting (to me at least) example of compound verbs, in this wiki page on Serial Verbs:
सत्तू खा लिया
sattū khā liyā
parched.grain eat take.pfv
"ate up the sattu"
vs.
बच्चे को खा डाला
bacce ko khā ḍālā
child.OBL DAT eat throw.pfv
"devoured the child"
How do these compound verbs develop?
