In two of the language families of India, Dravidian and Indo-Aryan, there is a common pattern of onomatopoetics, in their formation and also in part in their syntactic use, with proliferation of items in most of the languages for which there is adequate information. Comparison, based on the etymological dictionaries of the two families, yields some forty areal etymologies, i.e. overlapping which provides what within a single family would be considered clusters of etyma. Since the Indo-Aryan family seems not to inherit the pattern from Indo-European, diffusion is postulated from Dravidian both for the pattern and for some etymological items.
