The plural of wolf is wolves. Replace the final -f with -ves: “one wolf” becomes “two wolves.” Wolfs is not the ordinary plural noun in standard English.
The spelling change also reflects a sound change. Wolf ends with an f sound; wolves ends with a v sound followed by the plural ending.
Wolf and wolves in sentences
| Singular | Plural |
|---|---|
| A wolf is approaching. | Several wolves are approaching. |
| This wolf has a grey coat. | These wolves have grey coats. |
| The wolf was resting. | The wolves were resting. |
Changing the number may require changes elsewhere in the sentence, including this/these, is/are, and has/have.
Other nouns with a similar pattern
Leaf becomes leaves, knife becomes knives, and shelf becomes shelves. These examples can help you remember wolf and wolves.
However, not every noun ending in f or fe changes to -ves. Roof becomes roofs, and belief becomes beliefs. Learn the plural of an unfamiliar word individually instead of treating the pattern as universal.
Plural and possessive forms
- wolf: one animal.
- wolves: more than one animal.
- wolf’s: belonging to one wolf, as in “the wolf’s track.”
- wolves’: belonging to several wolves, as in “the wolves’ tracks.”
An apostrophe is unnecessary in an ordinary plural: “We saw three wolves,” not “three wolf’s.”
If possession sounds awkward or unclear, use an of phrase: “the tracks of the wolves.”
Wolf as a verb
Wolf can also mean to eat quickly, usually in the expression “wolf down.” Its third-person present form is wolfs: “He wolfs down his lunch.” Its past tense is wolfed.
That verbal form does not change the plural animal noun. “He wolfs down lunch” and “The wolves are resting” use different grammatical forms of the same spelling family.
Practice
Choose a form: “Three ___ crossed the path.” “The ___ paw was injured.” “He ___ down breakfast.”
Answers: wolves; wolf’s; wolfs.
Use the whole subject to choose the verb
“A pack of wolves was nearby” normally treats pack as the head of a singular subject. “The wolves were nearby” has wolves as its plural head. Collective-noun agreement can vary with English variety and meaning, but the plural wolves itself remains unchanged.
“Each of the wolves has a tracking label” uses singular has with each. Do not agree mechanically with the closest visible noun.
A word-family comparison
Wolf/wolves resembles leaf/leaves and shelf/shelves. By contrast, chief/chiefs and roof/roofs keep f. Writing two small example groups can help you remember the distinction without assuming one rule covers every word.
Editing exercise
Original: “Two wolfs were resting. One wolves stood up, and the wolf’s moved away together.”
Edited version: “Two wolves were resting. One wolf stood up, and the wolves moved away together.” The first noun needs the irregular plural, the second needs a singular after one, and the final plural does not need an apostrophe.
Frequently asked questions
Is wolves singular?
No. Use wolf for one animal and wolves for more than one.
Why is wolfs sometimes correct?
It can be a verb form, as in “she wolfs down dinner.” It is not the ordinary plural of the animal noun.
