If you will? What does that expression mean?

Question

How do you use it in a sentence?

Answer 1

It's not a phrase I use often, it sounds abrupt to me.
I always think it sounds more like a command than a request.
(That's a personal opinion.)

"Follow me, if you will."
"I'm very busy today come back tomorrow, if you will."
"Consider the consequences of your actions, if you will."

It's a standard old-fashioned phrase that's survived up to the present day as a throwaway politeness.
"Will" is being used in its less normal and more archaic sense of "wish", and could just as easily be replaced with the equally pointless "if you wouldn't mind".
Of course, any speaker of such a phrase expects absolutely no deviation from his/her instruction, despite the apparent genteel politeness of the conditional clause.

Answer 2

It means......if you desire to do so.. eg. You can swim across the river, if you so will.Moreover, if you will something to happen ,you try to make it happen by using mental effort rather than physical effort.e.g. He looked at the telephone,willing it to ring.

Answer 3

I believe its meaning is similar to "please" or "if you please" (which is a shortening still of "if it pleases you" same as "s'il vous plait), like "If [only] you will it [to happen/occur]."

e.g.,
So yeah, I'll take ten points if you will.
