सोपानम् १६: इत्-संज्ञा, अनुबन्ध-लोपः & फ्लैग-सक्रियता (The Paninian It-Compiler)
Sopāna 16: Understanding how Pāṇini tags temporary instructional markers (Anubandhas) and elides them via तस्य लोपः (१.३.९) to leave pure phonetic kernels (गर्जँ ➔ गर्ज्, शप् ➔ अ, तिप् ➔ ति)
१. दर्शनम् — अनुबन्धः (इत्) किम्? (The Compiler Tag Architecture)
"उपदेशेऽजनुनासिक इत्। हलन्त्यम्। तस्य लोपः॥"
— अष्टाध्यायी (१.३.२, १.३.३, १.३.९)
An Anubandha or It is temporary metadata attached to roots, affixes, or augments. Like a factory barcode or garment price tag, it triggers specific compiler operations (e.g., triggering Guṇa, choosing Voice) before being clipped off!
1. संज्ञा (Tagging): A sūtra identifies the marker sound and designates it as It (e.g. हलन्त्यम् १.३.३).
2. विधि (Elision): तस्य लोपः (१.३.९) deletes the tag so only the pure sound enters Sanskrit speech!
In Stage 2 (Sopāna 15), we assembled the raw formula "गर्जँ + शप् + तिप्". In Stage 3, we execute the 2-step It-pruning process on all 3 components to synthesize the pure active verb: गर्ज् + अ + ति ➔ गर्जति!
