Included under the rubric of reduplication are "echo compounds", a South Asian areal feature, in which the first part of the reduplicated word is replaced by a stock item. The size of the replaced segment and the form of the stock item vary from language to language. In Sri Lanka Portuguese and Tamil the first syllable onset and vowel are replaced by ki(i). The meaning is 'etc.'
