Quick answer
Use Wendy's (with apostrophe) for the brand's possessive. Use its for possession and it's only for it is/it has. Make verbs agree with the grammatical subject. For pronouns, pick formal (his or her) or inclusive (singular they) and be consistent.
- Brand possessive: Wendy → Wendy's (Wendy's menu). Not Wendys.
- its = possession; it's = it is / it has. Expand to check.
- Collective nouns: decide whether the group acts as a single unit (singular verb) or as individuals (plural verb).
- Singular indefinite pronouns (everyone) → formal: his or her; inclusive: singular they.
Core explanation: the minimum checks
Run three quick tests before you accept a sentence: possession vs plural, contraction expansion, and subject identification for agreement.
- Possessive test: Can you say "the X of Y"? If so, use a possessive (Wendy's menu = the menu of Wendy).
- Contraction test: Expand it's → it is / it has; if that fits, it's is correct.
- Agreement test: Remove intervening phrases and match the verb to the main subject.
Apostrophes and brand names: Wendy's not Wendys
Keep the apostrophe in brand possessives. Dropping it usually turns a possessive into a misspelling or a confusing plural. Even when you mention multiple locations, write the brand name as it appears: two Wendy's locations.
- Add 's for possessive names → Wendy's menu.
- Plural of the full business name: two Wendy's locations (the apostrophe remains part of the name).
- No space before an apostrophe: Wendy's not Wendy 's.
- Wrong: Wendys has a new sandwich on the menu.
- Right: Wendy's has a new sandwich on the menu.
- Wrong: I ate at the Wendys' downtown branch yesterday.
- Right: I ate at Wendy's downtown branch yesterday.
- Casual wrong: Going to Wendys later - who's in?
- Casual right: Going to Wendy's later - who's in?
- Work wrong: Wendys franchise agreements need an update.
- Work right: Wendy's franchise agreements need an update.
Its vs it's: the contraction test
Replace it's with "it is" or "it has." If the sentence still makes sense, keep the apostrophe. Otherwise use its for possession.
- Write it's only for it is / it has (expand to check).
- Use its for ownership (its menu, its policy).
- In formal writing avoid contractions when possible, but the apostrophe rule doesn't change.
- Wrong: The restaurant changed it's hours without warning.
- Right: The restaurant changed its hours without warning.
- Casual wrong: Its been nonstop here tonight.
- Casual right: It's been nonstop here tonight.
- Work wrong: The company revised it's policy on refunds.
- Work right: The company revised its policy on refunds.
Tools that help without replacing your judgment
Grammar checkers flag mechanical issues fast, but you decide tone and meaning. Use suggestions as a starting point and apply the three tests on this page before accepting changes.
A good checker will label the rule (apostrophe misuse, pronoun agreement, or hyphenation) and offer copy/paste-ready rewrites so you learn as you fix sentences.
Subject-verb agreement: pick a reading and stay consistent
Find the true subject, not a nearby noun. Collective nouns can be singular or plural depending on meaning. Quantifiers affect the verb: "the number of" is singular; "a number of" is plural.
- Collective as unit → singular verb: The team wins every game.
- Collective as individuals → plural verb: The team are arguing about shifts.
- Quantifier rule: The number of applicants is high; A number of applicants are late.
- Work wrong: The team play their shifts tonight.
- Work right: The team plays its shifts tonight.
- Work wrong: A number of employees was late to the meeting.
- Work right: A number of employees were late to the meeting.
- School wrong: Each of the students were given a worksheet.
- School right: Each of the students was given a worksheet.
- Casual wrong: The group are meeting at Wendy's later.
- Casual right: The group is meeting at Wendy's later.
Pronouns: everyone, singular they, whose vs who's
Traditional grammar pairs indefinite pronouns with "his or her." Modern inclusive usage accepts singular they. For whose vs who's, expand who's → who is / who has to check.
- Formal: Everyone should submit his or her report.
- Inclusive: Everyone should submit their report.
- Whose = possessive; who's = who is / who has (expand to test).
- School wrong: Everyone should do they own work.
- School right: Everyone should do his or her own work.
- School modern right: Everyone should do their own work.
- Work wrong: Whos bringing the slides to the meeting?
- Work right: Who's bringing the slides to the meeting?
- Casual wrong: Their coming to Wendy's after class.
- Casual right: They're coming to Wendy's after class.
Try your own sentence
Test the whole sentence rather than a single phrase; context usually clarifies possession, contraction, and agreement.
Hyphenation, spacing, and small punctuation fixes
Hyphens join words into a single adjective before a noun. Spacing errors around apostrophes are common typos. A hyphen can change meaning (resign vs re-sign).
- Compound adjective before noun = hyphenate: well-known employee; after noun: no hyphen (the employee is well known).
- No space before apostrophes: Wendy's (not Wendy 's).
- Hyphen changes meaning: resign (leave) vs re-sign (sign again).
- Wrong: A well known sandwich was reintroduced at Wendy's.
- Right: A well-known sandwich was reintroduced at Wendy's.
- Wrong: Please re sign the form.
- Right: Please re-sign the form.
- Wrong: Wendy 's closure surprised staff.
- Right: Wendy's closure surprised staff.

FAQ
Is "Wendys" ever correct?
Not when you mean the brand or its possessive form. Write Wendy's. For multiple locations, write "two Wendy's locations" - the apostrophe stays as part of the official name.
Should I use "its" or "it's" in a business report?
Use its for possession (the company increased its revenue). Use it's only when you mean "it is" or "it has." Avoid contractions in formal reports for a more professional tone.
Can I use singular they for "everyone" in school essays?
Many instructors accept singular they. If your course prefers traditional grammar, use "his or her." When unsure, follow the instructor's guidance or the relevant style guide.
How do I know whether to treat "team" as singular or plural?
Decide by meaning: if the group acts as one unit, use singular verbs; if you mean individual members, use plural verbs. Stay consistent within the same piece.
What's the fastest way to check a sentence for these mistakes?
Do three quick checks: expand it's to "it is/it has"; try "the X of Y" for possessives; read the sentence aloud dropping extra phrases to test subject-verb agreement. Use a grammar checker for a fast second opinion and suggested rewrites.
