I just texted someone and my wording was, "Call them in an hour." When I looked back at my text according to English rules it should have been "a hour."
An when the preceding word contains only a vowel is what I was taught.
But in this situation "an" sounds much more appropriate.
English gurus chime in please![]()
Does it really matter? Were you texting a grammar Nazi who will never speak to you again if you got it wrong?
