🕵️ The Sneaky Logic Behind “A” and “An”


💁🏻 Don’t worry; it’s not that complicated. (But it’s not super obvious either.)


Generally, we use “an” for words that start with a, e, and i:

  • an apple 🍎, an alligator 🐊, an angry man 🤬

  • an elephant 🐘, an exit door 🚪, an endangered animal 🐋

  • an iguana 🦎, an individually-wrapped chocolate bar 🍫, an ice cream cone 🍦


Words that begin with “u” and “o” are slightly tricky:

If a word begins with “u” in which the “u” makes an [ uh ]sound, we use “an”:

  • an umbrella ☂️

  • an ugly duckling 🐥

  • an underwater camera 📸

BUT … if the “u” word starts with a [ you ] sound, we use “a”:

  • a unicorn 🦄

  • a university 🎓

  • a unique shirt 👕

  • a united country 🇺🇸

We use “an” for many words that begin with “o”:

  • an octopus 🐙

  • an orange 🍊

  • an obscure writer ✍️

⚠️ HOWEVER, we use “a” for words that start with “o” if they make a [ won ] sound:

  • a one-time fee 💸

  • a one-man army 💪

  • a once-in-a-lifetime opportunity 🍀


In summary, all of the following are correct:

  • an octagon

  • a one-hour break

  • an unmitigated disaster

  • a unisex changing room

  • an orangutan 🦧

  • an unfortunate side effect

  • a euphemism (an e-word that begins with a [yoo] sound)

  • an umpire staring at an umbrella bat
