English couldn’t be simpler. It’s probably the easiest language there is and can be. Any other language has 10-100x more complexity. However, English DOES have perhaps the largest vocabulary in existence, but few use it effectively. English is like a good programming language should be: extensive libraries for every imaginable purpose, easy-on-the-brain syntax.

In my experience usually dealing with people whose second language is English, the inability to speak or write English even close to properly is in my estimation evidence of simple lack of use or, more usually, some mental disorder or significantly below average intelligence. Smart people all over the world speak English very well often with a richer vocabulary than those born into it, though, lacking exposure to daily face-to-face interaction, they do poorly at idioms, slang and colloquialisms, all sounding rather well-educated – which they usually are!

I believe these observations are found to be essentially correct by most who have experienced International English in all its forms.

Vast vocabulary, yes, complicated, no.

He would sound full of sh*t even if he spoke perfect English.
