You don't have a bad memory
People who say they are hopeless with vocabulary are almost always using the worst available method and blaming themselves for the result. Repeating a word until it sticks is the slowest route into long-term memory, and it is the one everyone reaches for first.
What follows is a ten-minute routine. Not ten minutes as a minimum that quietly becomes an hour, ten minutes as the whole thing.
Hook the new word to something you already know
A foreign word arrives meaningless, attached to nothing. The trick is to give it something to hang from, and the more connections it has the easier it comes back.
The keyword method is the crudest version and works embarrassingly well. Find an English word that sounds like the Portuguese one, then build a picture that contains both.
Chávena is a cup.
It sounds like "shaven".
So: a man with a completely shaven head, drinking tea out of an enormous fragile porcelain cup.
Absurd is better than sensible here. Next time chávena turns up in a story, the shaven man arrives with it and you skip the translation step entirely.

Ask for a celular in a Lisbon shop and you will be understood, served, and quietly filed. None of these are hard words. They are just the wrong ones.
