There is always more to learn language.
When I meet new word, I look over the meaning and how to use it.
In a dictionary I find many use of it from the standpoint of grammar, construction and idiom.
I note these to memorize them, and also with using them I try making sentences which contents relate to me, then I newly have unfamiliar words.
So I look over them.
Learning language is very interesting for me, I wish I was in school student days again and used enough time to learn language.
