In addition, I agree with your immesion idea, but the problem is that I am an English teacher and my students pinpoint questions like these. So I should be completely prepared, agree?
So, my question is NOT aswered yet ...
Thans anyhow.
So why am i trying to help you?

You are the english teacher. I'm just a forestry worker. Crikey! If the english teacher doesnt know the answer we're really up the creek.
Can you fob the students off with a context argument. "What does the rest of the sentence/paragraph tell you about these words?"
My daughter spent 12 months in Sweden as a 16 year old. She tells me her english teacher in Sweden taught the class that deer have "antenna" (antlers), and that Australia is on the "wrong" (other) side of the world.
Sorry I cant give you better help.
I hope someone else can. (Now is that sentence past present or future)
