kaTatva
kathatva ( nt. ; to katham, with -tva; cf. Skt. kathaṃtā, rare), how-ness, manner : Gv 526.23 (prose) dharmadhātu-prakṛti-kathatvāyatana-m-ucitatvān na kṣaṇyante sarvaviṣayeṣu (bodhisattvāḥ); -ucitatvān can only be construed as part of preceding cpd. ( m. ‘Hiatus-bridger’); the text seems rather suspicious.
