The Locative -7th case ending is not elided after a stem ending in a consonant or a short a when the compound is a Name.,
Thus युधिष्ठिरः, त्वचिसारः, गविष्ठिरः ॥ Though गो does not end in a consonant, yet it retains its Locative ending by virtue of 8.3.95 (गवियुधिभ्यां स्थिरः) which shows by implication that गवि is governed by this rule. So also अ ending words: as अरण्येतिलकाः, अरण्येमाषकाः, वनेकिंशुकाः, वनेहरिद्रकाः, वनेबल्बजकाः, पूर्वाह्णेस्फोटकाः, कूपेपिशाचकाः ॥ Why do we say \after a word ending in a consonant or अ\? Observe नद्यां कुक्कुटिका = नदीकुक्कुटिका, भूम्यां पाशाः = भूमिपाशाः ॥ Why do we say 'when a Name'? Observe अक्षशौण्डः ॥
Vart:- The Locative ending is not elided after हृद् and दिव्; as : हृदिस्पृक्, दिविस्पृकः ॥,
