The affix yat comes in the sense of 'its share' or 'its duty' after the word dūta in the Genitive -6th-Case in construction, in the chandas (Vedas).,
Thus दूत्यम् 'the share of a messenger or the work of a messenger'. As यत्ते अग्रे दूत्यम् ॥ According to (VI. I. 213), the accent will be दू꣡त्यम्, but the accented Text reads दूत्यम्॑ ॥,
