Esse, Este ou Aquele.
When to use esse, este or aquele has been a subject of much confusion on my journey down the Portuguese tree. Today I came across this very useful blog post, which explains everything very clearly. Hopefully it will be useful to many here as well.
i try explain it. think you speak with your friend about a dress. if you say - este vestido é verde ( use este because the dress is near you) esse vestido é verde (use esse because the dress is near your friend) and aquele vestido é verde (use aquele because the dress is far from you and your friend).
este esta- show the object is near from someone speak.
esse essa - show the object is near from someone hear.
aquele/aquela - show the object is far from someone hear and speak.
