@Loh Jane,
Quote:is it acceptable to say that thanks vastly?
I surmise that this is the portion you are referencing, Jane.
Yes, it is acceptable under these conditions:
You are an ENL or a highly proficient ESL/EFL. Why? Because it is not at all common but it could happen, said in a manner that left little or no doubt that the speaker knew - it's word play.
My nieces and nephews play a little game where they transpose the first letters of, usually, a two word phrase, "gad birl". The other has to describe the actual, real phrase in English.
Do you know what it is?
Here's some more. There're easy written but they can be mind benders when they are only spoken. I'll give some as they sound rather than the real spelling.
You Nork
