   The loss of the reduplicative syllable in the perfect is sufficiently accounted for by the same occurrence in almost all the modern, and even some of the ancient branches of the Indo-Germanic family.

plural reduplicatives

1. grammarA word obtained by the process of reduplication.

   Grammatically, Malay uses reduplication for plurals (burung = bird, burung-burung = birds) and thus repeated words are commonly heard in Malay speech; in contrast, in English reduplicatives are much less frequent and often involve phoneme modulation (ding-dong; wham-bam).
