To-does vs. To-dos vs. To-do’s – Which is Correct?
When referring to multiple tasks or items on a list that need to be completed, the correct plural noun is to-dos. Both “to-does” and “to-do’s” are incorrect. “To-does” misuses the verb form, while “to-do’s” mistakenly applies an apostrophe for pluralization, a common grammatical error.
To-does, To-dos, or To-do’s – Which is Correct?
The confusion between “to-does,” “to-dos,” and “to-do’s” stems from a misunderstanding of how to form plurals for compound nouns and the misuse of apostrophes. The only grammatically correct option for a list of tasks is to-dos.
To-dos correctly forms the plural of the noun phrase “to-do,” which functions as a single unit meaning “a task that needs to be done.” It follows the standard English rule for pluralizing nouns by adding an ‘s’ to the end.
To-does is incorrect because “does” is a form of the verb “to do” (third-person singular present tense), not a plural noun. Using “to-does” in place of “to-dos” is a grammatical error, often arising from phonetic confusion.
Understanding the nuances between these verb forms is crucial, as further detailed in “Do” vs. “Does”.
To-do’s is also incorrect. The apostrophe in “to-do’s” suggests either possession (e.g., “the cat’s toy”) or a contraction (e.g., “it’s”). While apostrophes are sometimes used for plurals of single letters or numbers (e.g., “mind your p’s and q’s”), they are not used to form the plural of regular nouns or compound nouns like “to-do.” This is a common hypercorrection or a misapplication of apostrophe rules.
The Best Trick to Remember the Difference
To remember the correct form, think of “to-do” as a singular item on a list. When you have multiple items, you simply add an ‘s’ to make it plural, just like you would with “task” becoming “tasks.” An apostrophe indicates possession or a contraction; since you are neither showing possession nor contracting anything, an apostrophe is unnecessary and incorrect for a plural list of tasks.
Swap Test: Try replacing “to-dos” with a simple plural noun like “tasks.” If the sentence still makes sense, “to-dos” is likely correct. If you tried to use “to-does” or “to-do’s” and replace it with “task’s” or “taskes,” you’d immediately spot the error.
| Word | Part of Speech / Status | Meaning | Example |
|---|---|---|---|

| to-does | Incorrect | Grammatically unsound; misuses verb form | Incorrect: He completed all his |
| to-do’s | Incorrect | Misuse of apostrophe for pluralization | Incorrect: The project manager listed the week’s |
How to Use To-dos
“To-dos” is a widely used plural noun referring to tasks, duties, or activities that need to be accomplished. It is commonly found in contexts related to planning, productivity, and organization. The term is generally considered informal but perfectly acceptable in both casual and professional settings, particularly when discussing task lists, project management, or personal organization.
Example 1: Before leaving the office, I always make a list of my top three to-dos for the next day.
Example 2: The team reviewed the project’s outstanding to-dos during their morning stand-up meeting.
Example 3: Clearing out my inbox is usually high on my weekend to-dos.
What are the different forms of To-dos?
The word “to-do” functions as a noun phrase. Its forms are:
- Singular: to-do (referring to one task or item).
- Plural: to-dos (referring to multiple tasks or items).
For instance, you might say, “I have one important to-do left,” or “I have many important to-dos left.” The hyphen in “to-do” is crucial as it signifies that “to-do” acts as a single noun.
Etymology of the word To-dos
The word “to-do” originates from the verb phrase “to do,” meaning “to perform an action” or “to accomplish something.” Over time, especially in the early 20th century, the infinitive verb phrase “to do” began to be used substantively as a noun, often hyphenated, to refer to a task or an item that needs doing. The plural “to-dos” naturally followed by adding an ‘s’ in accordance with standard English pluralization rules for nouns.
Related Concepts
Understanding broader grammatical concepts, particularly those related to pluralization and word formation, helps clarify why “to-dos” is the correct form.
- Pluralization of Nouns: English nouns typically form their plural by adding -s or -es. Misapplying an apostrophe for pluralization (e.g., creating “to-do’s”) is a common error, but apostrophes are reserved for possessives or contractions.
- Compound Nouns: A compound noun is a noun made up of two or more words (e.g., “high school,” “mother-in-law,” “to-do”). When pluralizing compound nouns, the ‘s’ is usually added to the main noun (e.g., “mothers-in-law”). In the case of “to-do,” which acts as a single conceptual unit, the ‘s’ is added to the end of the entire phrase.

Frequently Asked Questions
Question 1: Why is “to-do’s” incorrect?
“To-do’s” is incorrect because an apostrophe is generally not used to form the plural of regular nouns in English. Apostrophes indicate possession (e.g., “the cat’s food”) or contractions (e.g., “it’s cold”). For the plural of “to-do,” you simply add an ‘s’ to the end.
Question 2: Can “to-do” be used as a singular?
Yes, “to-do” (hyphenated) is the correct singular form, referring to a single task or item that needs to be done. For example, “I have one urgent to-do before the end of the day.”
Question 3: Is “to-do list” hyphenated?
Yes, “to-do list” is correctly hyphenated. The hyphen connects “to-do” to function as a single adjectival unit modifying “list,” indicating a list of tasks that need to be done.
Conclusion
Navigating the nuances of English grammar can be tricky, but understanding the correct usage of “to-dos” is straightforward. Remember that to-dos is the universally accepted plural noun for tasks, while “to-does” and “to-do’s” are grammatical errors. By consistently using the correct form, you ensure clarity in your communication and uphold your professional reputation. A simple ‘s’ is all that’s needed to pluralize this common and useful term.
