This is a discussion I keep wanting to have with students when we use future simple language tense patterns. However, due to the fact that future simple is pretty basic-level stuff, I always have to bite my tongue.
“Do as you will.”
That can either mean “do what you will inevitably do” (because it is a definite future event, the simple future) or “do that which you will to do” (will in the sense of “wish”). To me it’s interesting to examine the relationship between the verb “to will” and its use as mode for discussing the future.
Like I said, nerdy.
