My Brazilian ex girlfriend used to start her ‘what if’ (hypothetical) questions with ‘E se‘ (And if) and while that’s just fine as she was speaking correctly in her own language, she would translate it into English and ask a ‘what if’ by starting with “And if…” which slightly amused me but only because I understood where she was coming from when she constructed the sentence.
Usually an example would come up while watching a movie, where she’d say “e se ele morreu?” and I would respond, “I don’t know, let’s just watch it,” because I’m annoying like that when watching a good film. In any event, the Portuguese hypothetical started to make sense as a way to get to the point, otherwise one would have to say something like “E o que aconteceria se…”
On a side note, my German ex-girlfriend used to say ‘oder‘ at the end of some sentences and from my basic German, I knew that meant ‘or’, which meant in my English-speaking brain that she was speaking strangely. I started then to add ‘or’ to the end of some of my sentences in English to bother her…but I failed because she thought it was normal. Go figure! Later, I found out that the ‘oder‘ tag means ‘right?’
