लुटः प्रथमस्य डारौरसः

in the periphrastic future, the three third-person endings become डा, रौ, रस्

In the periphrastic future (लुट्), the first triad of endings — the third-person तिप्, तस्, झि — are replaced by डा (singular), रौ (dual) and रस् (plural). The ट् and स् of डा are only markers, leaving आ. So लभ् "to obtain" builds लब्धा "he will obtain", the periphrastic third-singular the poem carries; the dual and plural would run लब्धारौ, लब्धारः. This is why the periphrastic future's third person looks unlike the third person of every other tense.
