-DIE, suff. Also -dy and in Cai. -dag.

It is used esp. in children's words or in personal names, and is commonest in n.Sc. Gen. found with nouns, less freq. with advs. as Hindie. In origin the suff. arises from the dim. suff. -ie, on analogy with words where the -d is organic, e.g. Sandie, Baldie, laddie, candy.
