@WBYeats,
Quote:According to your answer, does the word tutorial only apply or do words like lecture also apply as long as these words comply with the rule of having been used as a regular thing?
As far as I can see, it seems so, WB. However, certain words like 'lecture' don't seem to be used as much/at all in that manner.
"Bring your stuff to lecture."
We do do that for 'class' - "Bring your protractor to class".
Now you know the rule or perhaps, better, the nuance. It doesn't then follow that 'the' is impossible in every situation.
Example: Two students are discussing their class/tutorial. Just as they leave each other, one of them remarks,
A: Oh, remember to bring your protractor to the class/tutorial.
A's mind could be/could have been focused on "the class/tutorial that we have been discussing". It's become specific in A's mind because it is made specific by the relative clause, "that we have been discussing".
Or A might say,
A: Oh, remember to bring your protractor to class/tutorial.
The take away message here is that you will always find examples that appear to contradict certain "rules", but the problem is we don't know the nuance, we don't know what is going on in the speaker's mind. It all boils down to CONTEXT CONTEXT CONTEXT and then CONTEXT.
