दम्dam4Pto tame, subdue
दम्उ उपशमे
Class 4P
to tame, subdue
N.B. commenting on this dhātu, सिद्धान्त-कौमुदी says उपशम इत्य् ण्य्-अन्तस्य । तेन सकर्मको 'यम्, न तु शमि-वद् अकर्मकः "the word उपशम in दम्उ उपशमे is made from a ण्य्-अन्त-धातु । thus दम्उ is sakarmaka, unlike शम्उ which is akarmaka" । the word उपशम in दम्उ उपशमे is made from उप + शम्उ + ण्इ + घ्अण् and there is no vṛṣṇīndra because of HNV sūtra 397 । thus the sense is cause to be calm" or, in other words, tame, subdue ।" this उपशम is different from the उपशम in शम्उ उपशमे which is formed from उप + शम्उ + घ्अण् and which just means be calm ।"
HNV 541: शम्-आदीनां त्रिविक्रमः श्ये (the अ of the śam-ādis becomes trivikrama when श्य follows) ।
