The natural sciences
As far as a factual text needs them.
What holds these lists together
Not a degree course, but what really appears in an explanatory article, a field guide or a warning notice — from rocks and weather to birds, fungi and fish. The value lies less in the science than in the places where Portuguese draws its lines differently. O tempo is both time and weather, so o tempo está a mudar needs its context before you know whether to take an umbrella. Scientific compounds double their s where the second part begins with one, which English never does: a fotossíntese, o ecossistema, a biossegurança. A reader who knows the English word can still misspell every one of them.
