Question
What is the right word(s) to use regarding "Subject" to work on or discuss such as in "Subjects to study at the engineering course at the university" or "Today's subject to work on is Oyster"?
I learnt I could use "material" but not "asunto". I would like to know if there are other words I can use or should use.
Background
It looks "sujeto" in Spanish is about an individual/person or a grammatical instance (who/what) which takes verbs (S + V), and not about "subject" to talk about or work on.
