Ever paused mid-sentence wondering, “Is it yesterdays or yesterday’s?” You’re definitely not alone. This small grammar detail trips up even confident writers because it involves one of the trickiest parts of English: apostrophes.
In this guide, we’ll break down yesterdays or yesterday’s, explain which is correct, and show you exactly how to use each form in real-life writing. By the end, you’ll never second-guess yourself again.
Yesterdays or Yesterday’s: Which Is Correct?
Let’s clear it up right away:
- “Yesterday’s” (with an apostrophe) is usually correct
- “Yesterdays” (without an apostrophe) is rarely used and often incorrect
The confusion comes down to possession vs. pluralization.
Understanding Yesterday’s (With Apostrophe)
What Does “Yesterday’s” Mean?
“Yesterday’s” is the possessive form of yesterday. It shows that something belongs to or is associated with yesterday.
Examples:
- Yesterday’s weather was beautiful.
- I reviewed yesterday’s notes before the test.
- Did you attend yesterday’s meeting?
In all these cases, something is linked to yesterday, so the apostrophe is necessary.
When (If Ever) Is “Yesterdays” Correct?
Is “Yesterdays” Ever Used?
Technically, “yesterdays” is the plural form of yesterday, but it’s rarely used in everyday English.
You might see it in more poetic or literary contexts, such as:
- “We often dwell on our yesterdays.”
Here, “yesterdays” refers to multiple past days or memories, not possession.
Key Takeaway:
- Use “yesterday’s” for almost all practical writing
- Use “yesterdays” only when talking about multiple past days (rare)
Yesterdays or Yesterday’s Meaning Explained
To simplify:
