“ When duplication takes place to indicate 'almost like,' or 'similar to,' no change of vowel takes place. The forms কাদা কাদা, জ্বর জ্বর, ঠাণ্ডা ঠাণ্ডা, মানুষ মানুষ, etc., are examples. 4. In the class of duplication noticed below, there is this special peculiarity, that in the process of duplication, the original word without being repeated, is conjoined to a synonym of it. Agglutination of two seemingly different words, should not mislead us to consider the word as a Samāsa compound. The adverbs করেকম্মে, ভেবেচিন্তে, ফেলেছড়ে, বলেকয়ে, মেগেযেচে, etc., are fitting examples. ”
