Syntactician, grammarian or better yet most known as a linguist is a person who specializes in the study of grammars and syntax of the English language.
I really look up to people who could speak or write English fluently and to my dismay, finds more people who claims as one. Please do not claim you are such if you could not live up to it’s meaning. Please do not tell the whole world you are a liguist when I, a mere commoner, could even spot the errors in your grammar. Please don’t overdo your English. It’s sounds absurd! You tend to make a simple sentence too complicated for one’s comprehension. You tend to use deep vocabularies but you fail to consider their consistency. Rationality is a noun. Don’t use it as a verb. Get the drift? Although they meant the same, their usage are different. Think about it. 😉
If you can’t live up to my extremely low standard for a Syntactician, dare not tell me you are good with the Language nor boast around that you are one. Simple words of advice to keep you from losing face.
