Nirukta, Phonetic Variants, and Vedic Dhātu–Svara Taxonomy
तत्करोति तदाचष्टे हेतुमत्यपि णिर्मतः । धात्वर्थे कर्तृकरणाञ्चित्राद्याश्चापि धातवः ॥ ७३ ॥
tatkaroti tadācaṣṭe hetumatyapi ṇirmataḥ | dhātvarthe kartṛkaraṇāñcitrādyāścāpi dhātavaḥ || 73 ||
«វាធ្វើអ្វីនោះ» និង «វាប្រាប់ឲ្យដឹងអ្វីនោះ»—ដូច្នេះហើយ ធាតុ (កិរិយាមូល) ត្រូវបានកំណត់ ទោះបីមានន័យបង្កហេតុ (causative) ក៏ដោយ។ ចំពោះអត្ថន័យធាតុ មានធាតុខ្លះបង្ហាញអ្នកធ្វើ និងឧបករណ៍ ហើយក៏មានធាតុប្រភេទផ្សេងៗជាច្រើនផងដែរ។
Sanatkumara (teaching Narada in a technical exposition aligned with Vyakarana)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It frames precise speech (śabda) and correct understanding of action (karma) through Vyākaraṇa: knowing how roots convey agency and means supports clarity in dharma-practice and removes confusion that obstructs mokṣa-oriented discernment.
Indirectly: Bhakti is strengthened when scripture is understood without distortion. This verse emphasizes disciplined interpretation of words (dhātu-artha, causative sense), which protects devotional teachings from misreading.
Vyākaraṇa (grammar): classification of verbal-root meanings, including causative (hetumati) formation and how roots can denote agent (kartṛ) and instrument (karaṇa) as part of semantic analysis.
