Analysis. Compound: mūla "root" + pariyāya "method of exposition" + sutta "discourse". The sutta discusses the root standpoints (pariyāya) from which wrong views arise, chiefly the eternalist and annihilationist views, and the middle way between them.
Etymology. mūla from Proto-Indo-European *mel- "to grind", cognate with English "meal" and "mill", originally the ground base; pariyāya from pari- (around, complete understanding) + i- (to go), "a going-around", hence a comprehensive method or exposition; sutta from past participle of sīvati (to sew), "sewn" or "thread", hence a discourse strung together like beads.
