Kodagu meaning :father's brother or parallel male cousin, mother's sister's husband
Notes :Just like *t-and-, this root commonly refers to 'father' as an honourable mention. The original meaning differentiation may have been preserved in Kodagu, where appë = 'father', while ayyë = 'father's brother, male cousin'; none of the other languages present an equally clear picture. The only common PSDR stem is the one in *-n (*ajja-n, pl. *ajja-r).
