SH-R-TZ – ‘prolific, nether spiral movement/generation’ (‘urge to merge’)
The verb שרוץ [sherets] which [Moses] employs, springs from two contracted roots שר–רץ; the first, שר composed of the signs of relative and proper movement, or circular and rectilinear [spiral, worm-like], indicates an emission, a liberation, a detachment, a separation. The second, שץ characterizes a sort of movement, of vibration, recommencing and finishing, reptilian, being propagated by being divided: thus the compound שרץ contains every idea of propagative emission, of motive origin, or generative separation. This is the figurative and hieroglyphic meaning. In the literal sense, it is a reptilian movement, and in a wholly restricted sense, a reptile. (Hebraic Tongue Restored, Fabré d’Olivet, p. 50)
