256. A final n

A final n, whether of stem or of root, is less stable than any other consonant, where a weaker form is called for: thus, from rā́jan we have rā́jā and rā́jabhis, and in composition rāja; from dhanín, dhanī́ and dhaníbhis and dháni; from √han we have hathá and hatá, etc. A final radical m is sometimes treated in the same way; thus, from √gam, gahí, gatám, gatá, gáti.
