🧑🎓 "I'm glad you can come" or "I'm glad you could come"? ENGLISH IN CONTEXT 👀
In this video I look at the context behind "can" and "could" in a very common social exchange — and at a broader principle that matters for both learners and teachers: a grammatically correct expression is never simply "wrong". It may be unsuitable in a particular context, but that's a very different thing, and the distinction matters.
There's also a bonus point for teachers: the video touches on the common textbook rule that "could" can only be used for general past ability, and "was/were able to" is required for ability on one specific occasion. The expression "I'm glad you could make it" shows clearly why that rule is an oversimplification.
What this video covers:
"Can" vs "could" in social invitations — what's the actual difference?
Why the timing of the conversation determines which form to use
Why teachers should be cautious about labelling grammatically correct expressions as "wrong"
Why the "could vs was/were able to" rule is more complicated than textbooks suggest
