Questions & Answers about Esta camisa azul es muy bonita.
Why is it esta and not este?
Esta means "this" and is used here because it describes camisa (shirt), which is a feminine word. If you were talking about a masculine word like vestido (dress), you would use este, as in este vestido.
Why does the sentence say camisa azul instead of azul camisa?
Does the color azul need to change to match the feminine word camisa?
