When you mean “many” or “a large amount,” the correct spelling is always lots — no apostrophe. Writing “lot’s” to mean “many” is a grammar error in every register of English, formal or casual. There is no context in which “lot’s of people” or “lot’s of time” is correct.
Lot’s (with an apostrophe) is a possessive form. It means something belongs to a specific lot — a plot of land or an assigned place. That use is real and valid. But it is narrow, and it never applies when you are talking about quantity.
The Rule Behind the Rule
The confusion comes from a fundamental misunderstanding of what apostrophes do.
An apostrophe has exactly two jobs in English: it marks possession (the dog’s leash, the car’s engine), and it marks contractions (it’s, don’t, she’s). An apostrophe never makes a word plural.
This pattern of incorrectly adding apostrophes to plurals is common enough that it has a name: the greengrocer’s apostrophe, named after handwritten produce signs reading “apple’s,” “banana’s,” and “tomato’s.” It appears across all kinds of writing — in emails, signs, menus, and social posts — but it is always wrong. “Lots” is a regular plural noun. It needs no apostrophe for the same reason “apples” and “chairs” need no apostrophe.
Lots of apples. ✔
Lot’s of apple’s. ✗
When to Use “Lots”
Lots functions in two standard ways in American English.
As a quantifier before “of”: The most common use. It means “many,” “a large amount of,” or “a great deal of,” and it modifies a following noun.
There are lots of seats left.
We have lots of work to do before the deadline.
She made lots of friends during her first year.
As an adverb modifying an adjective or comparative: Less commonly discussed but fully standard. Lots can intensify a comparison.
The second version is lots better than the first.
She’s feeling lots more confident after the practice run.
In both uses, no apostrophe is ever needed or correct.
When “Lot’s” Is Correct
Lot’s (apostrophe + s) is the possessive form of the noun lot — meaning a plot of land, a designated area, or a group of items sold together. It shows that something belongs to a specific lot.
The parking lot’s entrance was blocked by construction. (the entrance belonging to the lot)
The vacant lot’s fence has been in disrepair for years. (the fence belonging to the lot)
The auction lot’s description was misleading. (the description belonging to the auction lot)
This is correct and necessary in these cases. But notice that none of these sentences involve quantity. Lot’s as a possessive refers to a physical place or a grouped collection — never to “many.”
What about the possessive plural? When multiple lots collectively possess something, the apostrophe goes after the s: lots’.
The two vacant lots’ owners were contacted about the development project.
This form is rarely needed but correct when it is.
The “Alot” Error — A Related Mistake
Closely connected to the lots/lot’s confusion is a separate, extremely common error: writing “alot” as a single word.
Alot is never a word in standard English. The correct form is always two words: a lot. If you want a single-word alternative, use lots.
I have a lot of work to do. ✔
I have lots of work to do. ✔
I have alot of work to do. ✗
This error comes from the same instinct as the apostrophe error — writing quickly and phonetically without stopping to check the written form. Neither “alot” nor “lot’s” (in the plural sense) appears in any major dictionary as a standard spelling.
A Note on Formal Writing
Both lots of and a lot of are informal in register. They are perfectly standard in conversation, emails, journalism, and most everyday writing — but in academic papers, formal reports, legal documents, and professional publications, they are generally replaced with more precise alternatives:
many, numerous, a great deal of, a significant number of, an abundance of, considerable
Lots of students failed the exam. (casual, appropriate for informal writing)
Numerous students failed the exam. (formal alternative)
A great deal of preparation went into the event. (formal alternative to “lots of preparation”)
If you are writing under a style guide or for a formal audience, check whether lots of fits the register before using it.
The Origin of “Lot”
Lot traces to Old English hlot, meaning a share, a portion, or an object drawn by chance — as in “casting lots,” the ancient practice of drawing objects to make decisions by chance. That original meaning of “a portion or share” is why “a lot of something” came to mean “a large portion or quantity of something.” The plural lots extended this to mean “many portions” — effectively, “a great deal.”
The phrase “lots of” as a casual equivalent to “many” developed from this sense of multiple portions adding up to a large whole. It has been in widespread use since the mid-19th century and is firmly established in standard English today.
Common Mistakes and Quick Fixes
Mistake: Thanks lot’s for the help.
Fix: Thanks lots for the help. (quantity/intensity, no apostrophe)
Mistake: There’s lot’s to do before the event.
Fix: There’s lots to do before the event.
Mistake: I have alot of questions.
Fix: I have a lot of questions (two words) — or I have lots of questions.
Mistake: The two lots’ owners disagreed about the fence line.
Status: This is actually correct — lots’ is the possessive plural of lots (multiple plots of land). No fix needed.
Mistake: Using “lots of” in a formal academic paper.
Fix: Replace with many, numerous, or a significant number of depending on context and precision needed.
Quick Substitution Test
Ask yourself one question: can you replace the word with “many” and have the sentence still make sense?
There are lots of options available. → There are many options available. ✔ → Use lots, no apostrophe.
The parking lot’s entrance is narrow. → The parking many’s entrance is narrow. ✗ → This is a possessive; use lot’s.
If “many” fits, apostrophe does not belong. If “belonging to the lot” fits, apostrophe belongs.

FAQs
Is “lot’s” ever correct?
Yes — in one specific case. Lot’s is the possessive form of lot when a single piece of land or designated area owns something: the parking lot’s capacity, the corner lot’s overgrown fence. It is never correct when you mean “many” or “a large amount.”
Does “lots” need an apostrophe?
No, never. Lots meaning “many” is a regular plural noun. Plural nouns in English do not take apostrophes. Writing lot’s to mean “many” is the same error as writing “apple’s” to mean “apples.”
Is “alot” a word?
No. Alot is not a word in any variety of standard English. The correct forms are a lot (two words) or lots (one word, no apostrophe).
Is “lots of” formal enough for professional writing?
In most everyday professional writing — emails, memos, journalism — yes. In academic writing, legal documents, or formal reports, use many, numerous, a great deal of, or a significant number of instead.
What is the possessive plural of “lot”?
Lots’ — apostrophe after the s. Used when multiple lots (plots of land) collectively possess something: The two lots’ owners met to discuss the property line.
What is the “greengrocer’s apostrophe”?
It is the widely documented habit of inserting apostrophes into regular plural nouns: “apple’s” for “apples,” “banana’s” for “bananas,” “lot’s” for “lots.” The name comes from handwritten produce signs. The underlying error in every case is treating an apostrophe as a plural marker, which it is not.
The Bottom Line
Lots (no apostrophe) means “many.” Lot’s (apostrophe) means something belonging to a specific lot. In the quantity sense, the apostrophe is always wrong — not informal, not optional, but wrong. The underlying rule is simple and extends far beyond this one word: apostrophes mark possession and contractions. They never make plurals. Internalize that rule and neither “lot’s of people” nor any other greengrocer’s apostrophe will make it into your writing again.
Conclusion
Keep the Rule Simple
When you’re counting or estimating, reach for “lots,” no apostrophe attached. Save “lot’s” for the rare moment when a piece of land actually owns something. That one distinction, plural versus possessive, is all you need to get this right every time.
