How to improve English writing and speaking power
Forget these incredibly technical terms.

I went to school at a time when English grammar was a required partof everyone's education; we studied it for all 8 years of grade school. Never did I come across these terms. Let the linguistic experts deal with them, and just keep the basic words in mind - noun, verb, adjective, adverb, conjunction, preposition:

A noun is a thing.
An adjective describes the thing.
A verb is what the thing does.
An adverb tells how the thing does it.
A conjunction connects the thing with another thing.
A preposition also connects a thing with another thing.

These are rough-and-ready definitions, but with them in mind, you should be ok.

Had to learn Kazakh language for 6 months - I thought I am going to die...but I am still alive
Since the first day there I MUST speak and think very quickly - it was the best training for my language skills => you just have to be in situation when you have no rights to make even a single mistake
