This study presents a computational morphological analysis of the Torah (Five Books of Moses) as a closed linguistic corpus of 76,584 tokens. Every word is decomposed into three structural layers: a foundation root (semantic anchor), a mandatory root (stable consonantal skeleton), and an expansion layer (morphological extensions). The central finding: morphological expansion is governed by a restricted "control alphabet" of 10 letters -- EmetNiyahu (aleph, mem, tav, nun, yod, he, vav) plus BKL (bet, kaf, lamed) -- accounting for 99.87% of all 97,599 extension tokens (p Prophets > Writings), while Biblical Aramaic shows the same YHW mechanism but no significant narrative clustering (Z=0.39). All data from Sefaria.org. Complete code provided. Fully reproducible.
