Definition of Foot and Feet
In English, nouns typically form their plural by adding an “-s” or “-es” to the singular form. However, some nouns, like “foot,” follow irregular pluralization patterns. Understanding these irregularities is essential for accurate communication.
Foot
The word “foot” (singular) refers to the lower extremity of the leg below the ankle, on which a person stands or walks. It can also be a unit of measurement, equal to 12 inches.
Feet
The word “feet” (plural) refers to more than one foot. It is the irregular plural form of “foot” and is used when referring to multiple lower extremities or multiple units of measurement.
The classification of “foot” is a common noun, specifically a concrete noun, as it refers to a tangible object. Its function in a sentence can vary, acting as a subject, object, or part of a prepositional phrase. The context determines whether you use the singular “foot” or the plural “feet.”
Structural Breakdown of the Pluralization
The pluralization of “foot” to “feet” is an example of a morphological change known as vowel mutation or ablaut. This means the change in the word’s form occurs through an alteration of the vowel sound within the word, rather than adding a suffix.
Here’s a breakdown:
- Singular: foot (pronounced /fʊt/)
- Plural: feet (pronounced /fiːt/)
The vowel sound changes from a short “u” (/ʊ/) in “foot” to a long “ee” (/iː/) in “feet.” This type of irregular pluralization is a remnant of older forms of English and Germanic languages, where vowel changes were more common in forming plurals.
Other examples of this type of irregular pluralization include:
- tooth → teeth
- goose → geese
- mouse → mice
- louse → lice
These words share a similar pattern of vowel change in their plural forms, reflecting a historical linguistic process rather than a consistent rule.
Types and Categories of Noun Pluralization
English noun pluralization can be categorized into several types:
Regular Plurals
Most nouns form their plural by adding “-s” to the singular form. For example:
- cat → cats
- dog → dogs
- book → books
Nouns Ending in -s, -x, -ch, -sh
Nouns ending in “-s,” “-x,” “-ch,” or “-sh” typically add “-es” to form their plural. For example:
- bus → buses
- box → boxes
- church → churches
- dish → dishes
Nouns Ending in -y
Nouns ending in “-y” preceded by a consonant change the “-y” to “-i” and add “-es.” For example:
- baby → babies
- city → cities
- story → stories
Nouns Ending in -o
Some nouns ending in “-o” add “-es,” while others add only “-s.” There is no definitive rule, so it’s best to memorize these. For example:
- potato → potatoes
- tomato → tomatoes
- photo → photos
- piano → pianos
Irregular Plurals
Irregular plurals do not follow the standard rules and often involve vowel changes or other alterations. “Foot” and “feet” fall into this category.
Other examples include:
- man → men
- woman → women
- child → children
- person → people
Uncountable Nouns
Uncountable nouns (also known as mass nouns) typically do not have a plural form. For example:
- water
- air
- sand
Nouns with the Same Singular and Plural Form
Some nouns have the same form in both singular and plural. For example:
- sheep
- deer
- fish (often, but “fishes” can be used to denote different species)

Usage Rules for Foot and Feet
The key rule is to use “foot” when referring to a single foot and “feet” when referring to more than one. However, there are some nuances to consider.
Referring to Body Parts
When talking about the body part, use “foot” for one and “feet” for multiple.
- Correct: He hurt his foot.
- Correct: Her feet are cold.
Measurements
When using “foot” or “feet” as a unit of measurement, the rules can be slightly different. In some cases, “foot” is used as an adjective describing a measurement, even if it’s more than one foot.
- Correct: The table is three foot long. (Here, “foot” acts as an adjective modifying “long.”)
- Correct: The building is 100 feet tall. (Here, “feet” is used as a noun indicating the measurement.)
However, it’s generally safer and more grammatically sound to use “feet” when referring to measurements greater than one.
Compound Nouns
In compound nouns, the singular form “foot” is often retained, even when referring to something plural.
- Example: football (even though it involves two feet, it remains “football,” not “feetball”)
- Example: footbridge
Figurative Language
In some idiomatic expressions, “foot” or “feet” have specific meanings that don’t directly relate to the physical body part. These expressions should be learned as individual phrases.
- “Get off on the wrong foot” (to start something badly)
- “Put your foot down” (to be firm or assertive)
- “Sweep someone off their feet” (to charm someone greatly)
Common Mistakes with Foot and Feet
One of the most common mistakes is using “foot” as the plural form. Here are some examples of incorrect and correct usage.
| Incorrect | Correct | Explanation |
|---|---|---|
| He hurt his both foot. | He hurt both his feet. | “Feet” is the plural of “foot.” |
| The table is three feet long. | The table is three foot long. | In this specific measurement context, “foot” can be used as an adjective. However, “feet long” is also correct. |
| She has a small feet. | She has small feet. | “Feet” is the plural form. |
| He has a pain in his feet. | He has a pain in his foot. | If the pain is in one foot, use the singular “foot.” |

| He measured the room in foot. | He measured the room in feet. | “Feet” is the plural form for measurements. |
