Twice as expensive as VERSUS Twice more expensive as


Hello Teachers,

Please see the following:

[color=blue]My book is twice as expensive as your book.

My book is twice more expensive than your book.

Is there any difference between the two?

Thanksin advance



The first sentence is good, the second is not.


Hi Jupiter

You could possibly say “twice more” to mean “two additional times”. For example: He rang the bell twice more.
But, generally speaking, I’d say “twice more than” would not be used by native speakers. It sounds odd to me.



Following on what Yankee has imlpied, one of the reasons ‘twice more expensive than’ is not good English is that 'twice more expensive than’ could logically be interpreted to mean ‘three times as expensive as’.




Did he ring the bell three times altogether?



Hi Tom

It’s not possible to know from my sentence how many times he rang the bell.

If he’d already rung the bell 5 times and then decided to ring twice more, it would end up being a total of 7 times, for example.
