a) Gnostic/gno - "to know" implies ones perception...consenting to anything suggested tempts one to ignore gnostic for gnosticism, hence being tempted to get knowledge from another.

b) Gibberish/gibber - "to speak rapid and inarticulate"...all words suggested imply artifice within perceivable sound, and tempt one to rapid/rapere - "hurry away, carry off, seize".

That's why few suggest words, which many carry off into endless conflicts of reason against each other. Whatever word suggested...others start building opinions on it. That building process implies gibberish aka the tower of babel...always collapsing upon its foundation.
