de + este = deste, de + esse = desse, The word " deste has the same meaning of "este" and desse has the same meaning of "esse".
"Esse" is used to resume a term, an idea or a prayer already mentioned, as in the following example: "The Earth revolves around the Sun, that movement is known as translation."( A Terra gira em torno do Sol, esse movimento é conhecido como translação) . "Este," in turn, introduces a new idea, not yet mentioned, as can be seen in the phrase "This argument that men do not cry is so exceeded."( Este argumento que homens choram é tão ultrapasado)
"este" can also indicate proximity of the speaker, while "esse" gives the listener's proximity idea. Consider the sentences: a) "This shoe belongs to me"( este sapato me pertence), b) "When you bought that shoe are you using?"( Quando você comprou esse sapato que . In (a), the shoe is the speaker and is therefore closer to him. In (b), the shoe is of the listener.
The two terms are classified by the grammar as demonstrative pronouns and are used when the speaker wants to clarify the identity of a referent (name), resume content and localizálo in time and space. Among these functions, the most important is to resume already mentioned ideas and help text joint. The rule is basically the same for deste" e "desse", "isto" e "isso" e "disto" e "disso".
So in this case if you said "I like this café " or I like this coffee, both answers would be correct ? What if you were in a café with a coffee in front of you and you say "Eu gosto desse cafe" ? Wouldn't the person being talked to then have to clarify whether you are speaking about the coffee shop itself or the coffee ?
Ambiguity is unavoidable. It's a fact of life. If you're lucky, the person makes a gesture to indicate which one they mean, and if they don't, you can include gestures in your question. You mean the coffeeshop? (gesture broadly around yourself) Or do you mean the coffee? (point at a mug)
Looks like I am not alone here. It is very frustrating - these modules - as the Duolingo training modules do not give enough information for me to decided which Portuguese word is the correct one.
DUOLINGO = can you look into this PLEASE (I'm tearing my hair out over these modules - trying to guess where the article is (or is not) in order to decide on the correct Portuguese word)
