Are you going ‘thru’ something or ‘through’ something? And what’s the difference between the two? We’ll cover that in this article, plus teach you how to use both phrases correctly in a sentence.
The short answer is that ‘through’ is the only formally accepted way to spell the word. ‘Thru’ is more of an informal word that’s used in reference to fast food drive-thrus. Both words mean essentially the same thing.
Since we know that ‘through’ is technically the only correct formal way to spell the word, we could argue that ‘through’ is the right way to spell the word. ‘Thru’ is simply an informal way to spell the word. You might see it in text messages and in social media posts and memes. You’ll never see it in formal writing, however.
The difference between these two words, as you’ve just learned, is that one is the formal, acceptable version of the word. ‘Thru’ is the informal way to spell the word when referencing a fast-food drive-through.
