Commentary

The finite verb retains its accent in connection with सत्य when used in asking a question.
Thus सत्यं भोक्ष्य꣡से 'Truly will you eat'? सत्यमध्येष्यसे ॥ Why do we say 'in questioning'? Observe सत्यं वक्ष्यामि नानृतं 'I shall tell the truth, not falsehood', स॒त्यमिद्वा उ॒ तं व॒यमिन्द्र॑ स्तवाम्॒ ॥
