पदकाण्ड (1) a term used in connection with the first section of the Vākya- padīya named ब्रह्मकाण्ड also, which deals with padas, as contrast- ed with the second section which deals with Vākyas; (2) a section of the Așțadhyāyī of Pāņini, which gives rules about changes and modifications applic- able to the pada, or the formed word, as contrasted with the base (अङ्ग) and the suffixes. The section is called पदाधिकार which begins with
the rule पदस्य P.VIII.1.16. and ends with the rule इडाया वा VIII. 3. 54.
पदकार lit. one who has divided the Samhitā text of the Vedas into the Pada-text. The term is applied to ancient Vedic Scholars शाकल्य, आत्रेय, कात्यायन and others who wrote the Padapātha of the Vedic Samhitās. The term is applied possibly through misunderstanding by some scholars to the Mahābhāsyakāra who has not divided any Vedic Sam- hitā,but has, in fact, pointed out a few errors of the Padakāras and stated categorically that gra- mmarians need not follow the Pada- pāțha, but, rather, the writers of the Padapāțha should have follow- ed the rules of grammar. Patañ- jali, in fact, refers by the term पदकार to Kātyāyana, who wrote the Padapātha and the Prātiśākhya of the Vājasaneyi-Samhitā in the following statement--न लक्षणेन पदकारा अनुवर्त्याः। पदकारैर्नाम लक्षणमनुवर्त्यम्। यथालक्षणं पदं कर्तव्यम् M. Bh. on P. III.1. 109; VI. 1. 207; VIII. 2.16; cf. also अदीधयुरिति पदकारस्य प्रत्याख्यानपक्षे उदाह- रणमुपपन्नं भवति ( परिभाषासूचन of व्याडि Pari. 42 ) where Vyādi clearly refers to the Vārtika of Kātyā- yana ' दीधीवेव्योश्छन्दोविषयत्वात् ' P. I. 1.6 Vārt. I. The misunder- standing is due to passages in the commentary of स्कन्दस्वामिन् on the Nirukta passage I. 3, उब्वट- टीका on ऋक्प्रातिशाख्य XIII. 19 and others where the statements referred to as those of Patañjali are, in fact, quotations from the Prā- tiśākhya works and it is the writers of the Prātiśākhya works who are referred to as padakāras by Patañ jali in the Mahābhāsya.
