A is diffrent from B. can we use from in this sentence?
the other question is below
The difference between A and B is.... can we use between word?
In BE, 'from' is strongly preferred (I mean, some people will 'tut' if you say 'than'). I admit that to my ear, 'than' seems rather infelicitous (I'll put it no more strongly than that ), but more and more people are using it.
