Commentary
The affix खश् comes after the verbs ध्मा 'to blow' and धे 'to suck' when नासिका 'nose' and स्तन 'breast' are in composition with them as object.
The rule of yathasankhya as given in 1.3.10 does not however, apply here. For स्तन is compounded with धेट्; as (स्तन + धे + खश् = स्तन + मुम् + धे + शप् + खश् = स्तन + म् + धय् + अ + अ) = स्तनन्धयः 'an infant' (sucking the breast).
But नासिका is compounded with both ध्मा and धे; as नासिका + ध्मा + खश् = नासिक + म् + धम + अ 6.3.66 and (67); 7.3.78 = नासिकन्धमः 'blowing and breathing through the nose'. So also नासिकन्धयः 'drinking through the nose'.
