Koch

The name Koch simply means “power” in Hebrew, as כח kḥ koach. That’s pretty in-your-face, and quite befits the style of the obnoxious Koch brothers. The English variant is Cook, but it doesn’t work as well.

Hebrew kḥ = power

כח kḥ koach : force, might, power, powerful, strength, ability, substance, wealth, a reptile — Old Hebrew (Strong)
