YSK: Use ‘a’ when the word starts with a _consonant sound_, and ‘an’ when it starts with a _vowel sound_
YSK: Use ‘a’ when the word starts with a _consonant sound_, and ‘an’ when it starts with a _vowel sound_ - Lemmy.World
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).
