Definition of Foot and Feet
The word “foot” has two primary meanings. Firstly, it refers to the terminal part of the leg, below the ankle, that is used for standing and walking.
Secondly, “foot” is a unit of length in the imperial and US customary systems, equal to 12 inches. This article focuses primarily on the anatomical definition, but we will also touch upon the unit of measurement.
The word originates from the Old English word “fōt.” Understanding the etymology can provide a deeper appreciation for the word’s evolution and usage.
“Feet,” on the other hand, is the plural form of “foot.” It refers to two or more of the anatomical feet. Like “foot,” “feet” can also refer to a measurement, indicating multiple units of the length of a foot.
The key difference lies in the number being represented: singular versus plural. The correct usage of these words is essential for clear and accurate communication.
Structural Breakdown: Singular to Plural
The transformation of “foot” to “feet” is a prime example of irregular pluralization in English. Unlike regular nouns that simply add an “-s” or “-es” to form their plural (e.g., “cat” becomes “cats,” “box” becomes “boxes”), “foot” undergoes a vowel change. The vowel sound shifts from the short “oo” sound in “foot” to the long “ee” sound in “feet.” This pattern is observed in several other irregular nouns in English.
This type of pluralization is a remnant of older forms of English and Germanic languages. It reflects a linguistic process known as i-mutation or umlaut, where the vowel in a word changes due to the influence of a vowel in a following syllable that has since been lost. While this process is no longer productive in English (meaning we don’t create new plurals this way), it explains the historical development of many irregular plurals we still use today. Understanding this historical context can help learners remember these seemingly arbitrary plural forms.
Types and Categories of Noun Pluralization
Nouns in English form their plurals in different ways. Understanding these categories helps in grasping the irregularity of “foot” and “feet.”
Regular Nouns
These nouns form their plural by adding “-s” or “-es” to the singular form. This is the most common type of pluralization in English.
For example, “book” becomes “books,” “chair” becomes “chairs,” and “dress” becomes “dresses.” The rules for adding “-s” or “-es” are generally straightforward and predictable.
Irregular Nouns
Irregular nouns do not follow the standard rules for pluralization. They may undergo vowel changes, add different suffixes, or remain the same in both singular and plural forms.
“Foot” (feet), “man” (men), “child” (children), and “mouse” (mice) are all examples of irregular nouns. These often require memorization, as their plural forms are not predictable from their singular forms.
Many irregular nouns have roots in older forms of English.
Zero Plural Nouns
These nouns have the same form in both singular and plural. Examples include “sheep,” “deer,” and “species.” The context usually makes it clear whether the noun is singular or plural.
Zero plural nouns often refer to animals or units of measurement. Their lack of plural marking can sometimes lead to confusion, but careful attention to context usually resolves any ambiguity.

Usage Rules for Foot and Feet
Using “foot” and “feet” correctly depends on whether you’re referring to one or multiple instances of the noun. Here’s a breakdown of the usage rules.
Singular Usage: “Foot”
Use “foot” when referring to a single foot, whether in the anatomical sense or as a unit of measurement. It is used with singular verbs and articles (a/an/the).
Plural Usage: “Feet”
Use “feet” when referring to two or more feet. It is used with plural verbs.
When using “feet” as a unit of measurement, it is typically used with numbers greater than one. For example, “two feet,” “five feet,” etc.
Exceptions and Special Cases
While “feet” is generally the plural of “foot,” there are some special cases and exceptions to consider. In compound adjectives, “foot” is often used in the singular form, even when referring to a measurement.
For example, “a six-foot-long table” (not “a six-feet-long table”). However, “He is six feet tall” is correct.
Another exception is when “foot” is used attributively (as an adjective) modifying another noun. For example, “foot traffic” refers to the traffic caused by people walking, not just one foot.
“Foot soldiers” refers to soldiers on foot. These cases highlight the versatility of the word “foot” and its adaptability in various contexts.
Common Mistakes with Foot and Feet
One of the most common mistakes is using “foot” as the plural form. For example, saying “I have two foot” instead of “I have two feet.” Another common mistake is using “feet” in singular contexts, such as saying “My feet hurts” instead of “My foot hurts.”
Here’s a table illustrating some common mistakes and their corrections:

Advanced Topics: Historical Linguistics
For advanced learners, exploring the historical linguistics behind the irregular pluralization of “foot” to “feet” can be fascinating. As mentioned earlier, the vowel change is a result of a process called i-mutation or umlaut, common in Germanic languages.
This process involved the raising and fronting of a back vowel (like “oo” in “foot”) due to the influence of an “i” or “j” sound in the following syllable. Over time, this following syllable was often lost, but the vowel change remained, resulting in the irregular plural forms we see today.
Comparing “foot” and “feet” to similar irregular nouns like “tooth” (teeth) and “goose” (geese) reveals a pattern. These words share a common Germanic origin and underwent similar linguistic changes.
Studying these patterns can provide insights into the evolution of the English language and the relationships between different languages within the Germanic family. Furthermore, understanding the historical context can aid in memorizing these irregular forms, as they become less arbitrary and more connected to a broader linguistic history.
Frequently Asked Questions
- Why is the plural of “foot” “feet” and not “foots”?
The pluralization of “foot” to “feet” is an example of irregular pluralization, a remnant of historical linguistic processes in Old English. It involves a vowel change (i-mutation) rather than the addition of a suffix like “-s” or “-es.” This pattern is common among certain nouns of Germanic origin.
- Is it ever correct to use “foots”?
No, “foots” is generally not considered a correct plural form of “foot” in standard English. However, in very rare and specific contexts, such as describing the bases or supports of furniture (e.g., “the table’s foots were wobbly”), it might be encountered, but this usage is highly uncommon and generally avoided.
- When should I use “foot” versus “feet” when referring to measurements?
Use “foot” for singular measurements and “feet” for plural measurements. For example, “The table is one foot long,” but “The table is three feet long.” Also, in compound adjectives before a noun, use “foot,” even if the measurement is plural: “a six-foot table.”
- Are there other nouns that pluralize like “foot”?
Yes, several other nouns in English follow a similar pattern of vowel change in their plural forms. Examples include “tooth” (teeth), “goose” (geese), “mouse” (mice), and “louse” (lice). These nouns share a common linguistic history and underwent similar processes of i-mutation.
- What is i-mutation, and how does it relate to “foot” and “feet”?
I-mutation (or umlaut) is a historical linguistic process in Germanic languages where a vowel changes due to the influence of an “i” or “j” sound in a following syllable. In the case of “foot,” the “oo” sound changed to “ee” due to a now-lost “i” sound in the plural form. This process explains why the plural is “feet” instead of “foots.”
- How can I best remember the plural form of “foot”?
One effective method is to associate “foot” and “feet” with other similar irregular nouns like “tooth” and “teeth.” Understanding the historical linguistic context (i-mutation) can also help. Additionally, practicing with examples and exercises can solidify your understanding and improve your recall.
- Can “foot” be used as a verb?
Yes, “foot” can be used as a verb, although it’s less common. It usually means to pay for something, as in “to foot the bill.” This usage is unrelated to the anatomical meaning of “foot.”
- Is it correct to say “footprints” or “feetprints”?
It is correct to say “footprints.” Although it is a plural concept usually (multiple prints of feet), the word “footprint” has become a standard term. The word “feetprints” is not a recognized word.
Conclusion
Mastering the pluralization of irregular nouns like “foot” requires understanding their historical roots and applying specific usage rules. “Foot” becomes “feet” due to a historical linguistic process called i-mutation, distinguishing it from regular nouns that simply add “-s” or “-es.” Remembering this distinction and practicing with examples will significantly improve your accuracy in using these words.
Pay close attention to context, especially when dealing with measurements and idiomatic expressions.
By understanding the nuances of “foot” and “feet,” you enhance your overall command of English grammar. Continue to practice and explore other irregular nouns to further refine your language skills.
Consistent application and review are key to solidifying your knowledge and confidently using these words in your writing and speech. Keep practicing, and you’ll be on your way to mastering even the trickiest aspects of English grammar!
