193. In compound words

In compound words, an altering cause in one member sometimes lingualizes a n of the next following member—either its initial or final n, or n in its inflectional or derivative ending. The exercise of the altering influence can be seen to depend in part upon the closeness or frequency of the compound, or its integration by being made the base of a derivative. Examples are: grāmaṇī́, triṇāman, urūṇasá; vṛtraháṇam etc. (but vṛtraghnā́ etc.: 195 a), nṛmáṇas, drughaṇá; pravā́haṇa, nṛpā́ṇa, pūryā́ṇa, pitṛyā́ṇa; svargéṇa, durgā́ṇi, usráyāmṇe, tryan̄gā́ṇām.
