Hello, everyone!  I once read a article about the functions of different parts of human's brain, and it said that different parts in human's brian dominate the storage for different kinds of words. 

I found that, for me, it is easier to remember nouns than to memorize adjectives or adverbs. 

If you have noticed this, which part of speech is simpler for you to remember or master? Also, does anyone have a robust method that could have me remember adjectives more efficiently?
