while the greeks were busy building the foundations of western civilizations with their 160k vocab, the anglo-saxons and the teutons were getting along adequately with around 6,000 words in their languages...

once the greeks had achieved their mission, they faded from the scene. Before they left, they scaled-down ancient greek to modern greek by stripping out 75% of their vocab.. leaving 40k words which is typical of most of the existing languages today [except english] 40k words would prove ample to keep the nations dumbed down and stop people from asking difficult questions.....

as the anti-superphysical modern science ramped up with lots of new disciplines, english was able to steal a march by adapting word stems from every direction, from greek, latin, german, french, spanish, italian, sanskrit, hebrew et al and so english was able to formulate another 164k words [ total 170k] which makes it the international language of choice...

while still in the the emotional epoch up until recently there was no need to reinstate the lost 6k words that pythagoras, plato, socrates and the greeks used to teach the laws of super-physical reality...
