suttanta is derived from sutta + anta. anta "end" apparently
functions as a semantically neutral suffix, cf. kammanta "action,
act," from kamma + anta. In the Pali canon sutta denotes the
Patimokkha, unlike the suttantas viz. the doctrinal parts of the
canon. This distinction is corroborated in by the canon itself.
