1. Which meaning should we assume when the adjective is used after "es" in a statement, such as "Aquel hombre es muy pobre"?
2. In usage number two in your explanation, where does the adjective go if it is describing a difference from a normal quality, as in "that sour cake" (maybe someone put in too much lemon and forgot the sugar).
3. How about adding the word "feo" to your list of words with two meanings? Here in Mexico it can either mean "ugly" or "very bad", although the second meaning is usually phrased as "Es feo".
Thanks!
