The affixes kṛtya and the affix tṛca are added to a root when fitness as regards the agent is implied (as well as in the affix liṅ (Benedictive) ).,
The force of च is to introduce the Potential (लिङ्) into this, from the last. Thus भवता खलु कन्या वोढव्या वाह्या or वहनीया, (kritya); or भवान् खलु कन्यया वोढा (trich); or भवान् खलु कन्यां वहेत् (lin) 'your honor is fit to marry the girl'.
Why specifically enjoin 'kritya' and 'trich' in the sense of fitness? They being enjoined universally, would a fortiori, be applied when fitness is to be denoted ? Because the लिङ् being specially enjoined to denote fitness, and being an Apavada, would have debarred kritya and trich, which being universal affixes, would give way. Nor can we, to prevent this contingency, take shelter under rule 3.1.94 of 'non-uniform affixes', for we have seen that that rule is not universally valid.,
