Ever been in the middle of a sentence and suddenly frozen because you didn't know which version of "either" was about to come out of your mouth? It’s a classic linguistic trap. One second you're talking about dinner options, and the next, you’re wondering if you sound like a snob or just someone who skipped English class. Honestly, it’s one of those words that makes you overthink your entire identity for a split second.
The reality is that how do you pronounce either isn't just a question of right or wrong. It’s a question of where you grew up, who you’re talking to, and how much "flair" you want to put on your vowels.
Some people swear by the long "E" sound (EE-ther). Others wouldn't dream of saying anything but the long "I" (EYE-ther). Neither is technically incorrect, but the history behind why we have two versions is actually pretty fascinating if you’re a word nerd. Or even if you’re just tired of your friends correcting you.
The Battle of EE-ther vs. EYE-ther
So, what’s the actual deal? If you look at the Cambridge Dictionary or the Merriam-Webster collegiate files, you’ll see both pronunciations listed. They don't prioritize one over the other because they are both "standard." However, the EE-ther pronunciation is significantly more common in American English.
Most Americans grow up using the long "E." It feels natural. It’s the default. If you walk into a grocery store in Ohio and say "EYE-ther," people might think you’ve recently returned from a semester abroad in London or that you’re trying a bit too hard to sound sophisticated.
British English is a different story. While both versions exist in the UK, the "EYE-ther" sound is much more prevalent there, particularly in Received Pronunciation (that "BBC English" sound). But even that isn't a hard rule. Language is messy.
Think about the song "Let's Call the Whole Thing Off." You know the one—Ira and George Gershwin wrote it back in 1937. "You say either and I say either, you say neither and I say neither..." It’s the ultimate proof that this debate has been annoying people for nearly a century. The song actually uses the pronunciation split to highlight class and cultural differences, which tells you everything you need to know about how we perceive these sounds.
Why Do We Have Two Ways to Say It?
English is essentially three languages wearing a trench coat. It’s a Germanic base with a massive amount of French and Latin shoved into it. The word "either" comes from the Old English ægther. Over hundreds of years, the spelling and the sound shifted.
During the Great Vowel Shift—a massive change in how English speakers pronounced their long vowels between the 1400s and 1700s—the word got caught in the crossfire. Some regions shifted the sound toward the "ee" (like "leaf" or "tree"), while others leaned into the "eye" sound.
Interestingly, there’s no specific "rule" in phonics that dictates one over the other here. Words like "height" or "sleight" use the "eye" sound, while "ceiling" or "receive" use the "ee" sound. "Either" just happens to be one of those flexible words that survived the shift with both versions intact.

Does it actually matter?
Not really. Unless you’re an actor trying to nail a specific regional accent, you can use whichever one feels comfortable. But there is a subtle social "vibe" attached to them.
- EE-ther: Sounds casual, American, straightforward, and friendly.
- EYE-ther: Can sound formal, British, emphatic, or academic.
If you’re giving a high-stakes presentation or performing Shakespeare, you might opt for "EYE-ther" for the clarity and "weight" it carries. If you're asking your roommate if they want pizza or tacos, "EE-ther" is probably your best bet.
Regional Quirks and Global Trends
In Canada, you’ll hear a mix. Because Canada sits at the intersection of British influence and American proximity, Canadians often flip-flop between the two without even noticing. It’s not uncommon for a Canadian to say "EE-ther" in one sentence and "EYE-ther" ten minutes later.
In Australia and New Zealand, the British influence usually wins out, making "EYE-ther" the dominant form. But as American media dominates TikTok and Netflix, the "EE-ther" sound is creeping into the vocabularies of younger generations globally.
It’s also worth noting that "neither" follows the exact same pattern. It’s almost universal that if you use the long "E" for either, you’ll use it for neither. Mixing them—saying "EE-ther" but "NYE-ther"—is rare and usually happens by accident. It sounds jarring to the ear, like wearing one sneaker and one dress shoe.
Common Misconceptions About the "Right" Way
People love to be right. They love it so much they’ll invent rules that don't exist. You might have heard someone say that "EYE-ther" is for the conjunction and "EE-ther" is for the pronoun.
That is completely made up.
Grammatically, the pronunciation has zero impact on the word's function. Whether you’re saying "Either of them can go" (pronoun) or "Either stay or leave" (conjunction), the sound is up to you.
Another weird myth is that "EYE-ther" is the "older" or "more original" version. Technically, the Old English pronunciation wouldn't sound like either of our modern versions. It would sound more like "AY-ther" (rhyming with "hey"). So, if you really want to be "original," you’re a few centuries too late.
How to Choose Your Pronunciation
If you’re still stressed about how do you pronounce either, here is a simple way to decide.
First, listen to the people around you. If you’re in a boardroom in New York and everyone is saying "EE-ther," just go with the flow. Mirroring the speech patterns of your environment is a natural human instinct that helps with communication.

Second, think about emphasis. If you want to really stress a choice, "EYE-ther" has a sharper, more biting sound. "I don't want either of those!" sounds a bit more dramatic with the long "I."
Third, just be consistent. The only way you really look "wrong" is if you struggle with it. Confidence is 90% of language. If you say it like you mean it, nobody is going to stop and correct you. And if they do? They’re probably the kind of person who corrects people's "who" vs "whom" at parties. You don't need that energy.
Practical Steps for Mastering the Sound
If you’re learning English as a second language, the "th" in either is actually the harder part than the vowel. It’s a voiced "th" (like "mother" or "this"), not a soft "th" (like "think" or "bath").
- Place your tongue between your teeth.
- Vibrate your vocal cords as you push air out.
- Transition quickly into the "er" sound.
If you want to practice the vowel shift, try saying this sentence out loud: "I will either take the train or either take the bus." Try it once with the "EE" and once with the "EYE." See which one feels more natural in your mouth. Most people find that one feels physically "easier" to say based on the shape of their jaw and their native dialect.
The Verdict on Either
The beauty of English is its flexibility. We don't have a formal "language academy" like the French do to tell us what’s legal and what’s not. We just talk, and eventually, the dictionaries catch up to us.
Whether you choose the American-leaning "EE-ther" or the more formal-sounding "EYE-ther," you are participating in a linguistic tradition that has been evolving for a thousand years. Neither is a mistake. Both are correct. The only real error is overthinking it to the point where you stop talking altogether.
Your Next Steps:
- Audit your own speech: Pay attention to which version you use naturally over the next 24 hours. You might be surprised to find you use both depending on the context.
- Listen to a podcast from a different country (like the BBC vs. an American NPR show) specifically to hear the "either/neither" divide in action.
- Pick one and stick to it for a week if you're trying to build a consistent "voice" for public speaking or professional settings.
- Ignore the "grammar police" who tell you one is superior; now you have the historical context to know they're just blowing smoke.
