प्रसम्भ्याम् जानुनोः ज्ञुः
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
जानुनोः → ज्ञुः / प्रसम्भ्याम्
Replace jānunoḥ with jñuḥ when it comes after prasambhyām. Inherited words (anuvṛtti) may add further conditions.
Commentary
After the words प्र and सम् there is the substitution of ज्ञु for जानु when forming the बहुव्रीहि समास ।
Thus प्रकृष्टे जानुनी अस्य = प्रज्ञुः, So also संज्ञुः ॥
