Commentary
The form इच्छा 'desire' is irregular.
The word is thus formed : इष् + श = इच्छ् + अ = इच्छा. The यक् ordained by 3.1.67 is not added, this is the irregularity.
Vart:- The following words are also irregularly formed :- परिसर्या 'perambulation'; परिचर्या 'attendance, service'; मृगया 'hunting'; अटाट्य 'the habit of roaming about as a religious mendicant'.
Vart:- From the root जागृ we have either जागरा or जागर्या 'waking'. The first is formed by the affix अ, the latter by श which brings in यक् 3.1.67.
