Whether you’re writing a sales proposal, staff memo or report to colleagues, you don’t want to make a mistake like this: The team’s effort deserved a F. You would be the one flunking!
The rule we learned as children was to use a before words that start with a consonant – a ball, a mitt, a tee – and an before words that start with a vowel – an apple, an enchilada, an orange. But that’s not quite the whole story.
It’s the sound that counts (which is why we’re more likely to make the mistake writing than speaking). Use a before words that start with a consonant sound – even if the letter happens to be a vowel:
• A European joke The E sounds like the y in your.
• A one-week trip The o sounds like the w in won.
• A unique situation The u sounds like the y in you.
Use an before words (or letters or numbers) that start with a vowel sound – even if the letter happens to be a consonant:
• An NFL game The N begins with an e sound (as does the F in the first example).
• An 80-year-old house The 80 begins with an a sound.
• An hour for lunch The h is silent; the word sounds like our.
H-words in which the h is unstressed or weak – words like historic and hypothesis – are a gray area. Both a and an are commonly used. One study noted that a is used more often with those words, but an is used often enough to be considered standard usage. Here at SKAR, following the AP Stylebook, we prefer a historic and a hypothesis.
