The affix yat comes in the sense of the descendant after the words rājan and śvasura,
This debars अण् and अञ् respectively. Thus राजन्यः 4.4.168 'a person of Kshatriya class'. This is the special meaning of the word; it does not mean 'the son of a Raja.' The word राजनः will mean 'the son of a King.' So also श्वशुरर्यः 'son of the father-in-in-law.',
