Demonstrative Pronouns and Adjectives

These words say THIS, THAT, THESE, and THOSE.
There are many words to say these things because of gender (masculine and feminine) and number (singular and plural). Plus, there are the pronouns which have accents, and the adjectives, which do not have accents. Six pronouns are neutral. You use when you don't know the gender. They do not need accents. They are esto,estos,eso,esos,aquello, aquellos. They share the plurals with the masculine plurals. This is all kind of hard, isn't it? Now add the fact that the Academia Real of Spain actually eliminated the need for the accents, but most books have not changed their rules yet. Oh well...Good luck on learning these vocabulary words.
