I think the importance of tones has to be regional because when i was questioning my hooyo on this with the example árdey s. Vs ardéy pl. And she didnt pronounce it like that she used for the plural the definite ardayada. Implying the indefinite plural would be ardayo
There are all sorts of regional idiosyncracies my mum uses for example one is how ball is said. Either kubbadda or balooniga but my mum says baloonti. And in koonfuur the word badar is used as another way to say food or meal kamid cunto and reeshiin. But in all dictionary entries i only find it meaning grain or cereal
