Is using "as from" correct English?
Many years ago in my first job, I made the mistake of writing "as from" instead of "as opposed to" in a document. To me it seemed normal usage (I must have learnt it from somewhere) but everyone else claimed it was not correct English.
Were they right?
Solution 1:
They were right:
I am tall as from short
For example, makes no sense whatsoever, I'm afraid.
You might say:
Prices will go up as from 1st January.
But that's the only use I can think of for it. Others may gainsay me.
