Why you should know: The ‘a’ vs ‘an’ conundrum is not about what letter actually begins the word, but instead about how the sound of the word starts.
For example, the ‘h’ in ‘hour’ is silent, so you would say ‘an hour’ and not ‘a hour’. A trickier example is Ukraine: because the ‘U’ is pronounced as ‘You’, and in this case the ‘y’ is a consonant, you would say “a Ukraine” and not “an Ukraine”.
Tip: when in doubt, sound it out(loud).
Thank you for coming to my TED talk.
Only when it’s needed.
With literacy rates in America “hold my beer” low and getting lower, maybe there’s a need.
Example: if people pluralize “email” different from “mail”, they may need to review.
I like how you tried to be a grammar snob and couldn’t even get your example right.
