As an English learner, I 've been taught that often should be pronounced without uttering the t. Of course, as years went by, I realised- thanks to Pr Jones and his sacrosanct English Pronouncing Dictionary- that the T could be uttered but this way was regarded as old-fashioned.
The question at the heart of the matter is: nowadays, who 's used to uttering the t ( ages, places, social backgrounds..) in often?
I noticed a T in Pink Floyd's song IF in Atom H mother? I'm iffy about the reason ofWater uttering the T: a question of style ? Or is it because of Water's seemingly POSH bakground?
I've heard it both ways - it may well be both a social and a dialectical difference.
