Theine

Dear Theine,

I do not accept you as a real word. 

Your close cousin, Theanine, I have no problem with. He actually appears to have a place in the world of tea.

Please stop appearing in otherwise well-written and interesting books on tea, trying to pass yourself off as your cousin. It's embarrassing for us all.

For anyone who might not know, Theanine is an amino acid especially found in green tea that gives it that kind of sweet taste (check it out ), while Theine is a "tea specific" word for caffeine (What am I a talking about, of course you all know this).
