Today we will look at the application of 8-3-19 लोपः शाकल्यस्य The वृत्तिः from Laghu Siddhanta Kaumudi is
अवर्णपूर्वयोः पदान्तयोः लोपो वा अशि
In the opinion of the teacher शाकल्यः, the letter ‘य्’ or ‘व्’ is elided when it occurs at the end of a पदम् and is preceded by the अवर्णः (‘अ’ or ‘आ’) and is followed by a letter of the अश्-प्रत्याहारः। Note: Since the elision (of the letter ‘य्’ or ‘व्’) is only in the opinion of the teacher शाकल्यः (and not in the opinion of all teachers), it implies that the elision is optional.

Below are two examples where this rule is applied:

Example 1 Bg3-22
नानवाप्तमवाप्तव्यं वर्त एव च कर्मणि
वर्ते is the लट् उत्तमपुरुषः एकवचनम् of dhatu √वृत् (वृतुँ वर्तने १.८६२)

वर्ते + एव
वर् त् अय् + एव । 6-1-78 एचो यवायावः
वर्ते gets पदसंज्ञा by 1-4-14 सुप्तिङन्तं पदम् and so does the form वर्तय् (by परिभाषा एकदेशविकृतम् अनन्यवत्)
Note that the letter following the य् belongs to the अश्-प्रत्याहारः
Since all the conditions to apply 8-3-19 लोपः शाकल्यस्य are now satisfied, the ending य् can be dropped
वर्त एव

Example 2
वने अासीत्
वनय् अासीत् । एचोऽयवायावः
वन आसीत् । 8-3-19 लोपः शाकल्यस्य

Questions:
1. In Example 1 above, after deriving the final form वर्त एव, the conditions seem ripe to apply 6-1-88 वृद्धिरेचि Can we proceed to apply वृद्धिसन्धिः here? If yes, why? If not why?

2. Spot the application of 8-3-19 लोपः शाकल्यस्य, if any, in the following snippets.
