The indeclinable word sāmi 'half' is compounded with a word ending in the affix kta and the resulting compound is tat-puruṣa ,
The word सामि being an avyaya, and not denoting any substance, cannot take the affixes of the second or any case. Therefore the anuvritti of the word द्वितीया would be inapposite in this aphorism.
As सामिकृतम् 'half-done.' सामिपीतम् 'half-drunk' सामिभुक्तम् 'half-eaten.'
The object attained by this samása is the same as in 2.1.25, namely, making them one word and taking one accent.,
