A feminine word having a penultimate k does not assume the masculine form.,
Thus पाचिकाभार्यः, कारिकाभार्यः, वृजिकाभार्यः, मद्रिकाभार्यः, मद्रिकाकल्पा, मद्रिकायते ॥ वृजिकायते, मद्रिकामानिनी, वृजिकामानिनी, वैलेपिकं (वैलेपिकाया धर्म्यं). This rule is an exception to all the previous rules 6.3.34 — 6.3.36 : and not only to 6.3.34.
Vart :- The rule applies to the क of the affix वु and the Taddhita क and not to every क ॥ Therefore the masculine transformation takes place here पाकभार्यः, भेकभार्यः ॥ The word पाका means \young\; and भेकी means 'action'.,
