I have been told (maybe erroneously) that the pronoun "an" should always be used with the word history. If this is correct then in my opinion it makes pronounciation rather difficult. For example :
"I was reading an history of the Jaguar Car Company."
as opposed to
"I was reading a history of the Jaguar Car Company."
I feel that using "an" encourages one to drop the h.
All advice will be gratefully received.
Thank you,
Paul.
