An and A

I am still confused about when to use an instead of a. Is it an hour or a hour and if someone is doing a master's degree in arts, is it an MA or a MA?


With single letters and groups of letters pronounced as letters, be guided by the pronunciation.


• a B road


• a KLM flight


But an A road, an FA cup final, an SAS flight (R.W. Burchfield, The New Fowler's Modern English Usage)


So it is an hour, an MA.
