Calfs or Calves | What’s the Correct Plural Form?

Common Mistakes updated on  January 22, 2024 2 min read

The correct plural form of the noun “calf” is “calves.”

This is the case whether you’re using “calves” to refer to the offspring of a domestic cow or the muscles behind your lower legs.

Examples: Calves in a sentence
We move the herd of calves into the barn every night.
After a difficult exercise session, my calves were sore.
Today, I learned that baby whales and elephants are also called calves.

Is it calve or calf?

The correct singular noun is “calf, not “calve.”

“Calf” has various meanings. It can be used to refer to a young cow or to the offspring of other animals, such as elks, elephants, and whales. But it can also refer to the area behind the lower leg and the muscles in this region.

Examples: Calf in a sentence
The young calf followed the other cows everywhere.
We saw a sperm whale with her calf during our whale-watching trip.
I had to take a break from soccer after I tore a calf muscle.
My right calf is bigger than my left one.

Some dictionaries also define “calf” as both “an awkward, silly boy or young man” and “a piece of ice detached from a glacier,” but these uses are less common.

The word “calve” (no “s”) is a verb that can refer to a cow giving birth or to a piece of ice becoming detached from a glacier or iceberg.

Examples: Calve in a sentence
The cow is expected to calve at some point today.
We witnessed a large glacier calve while on our expedition.

Calves vs calfs

“Calves” is the plural form of “calf,” regardless of what animal you’re referring to.

Examples: Calfs vs calves
The little calfs were so cute!
The little calves were so cute!

Similarly, the correct plural form for the area and muscles behind both legs is “calves.”

Examples: Calfs vs calves
I need to strengthen my calfs because they’re so weak.
I need to strengthen my calves because they’re so weak.

Although this area comprises multiple muscles, “calf” refers to the muscle group behind one leg and “calves” to those behind both legs.

Additionally, “calf muscles” can refer to either one or both legs. “Calf muscle” and “calf muscles” are sometimes used interchangeably, even though they refer to a group of muscles.

The term “calves muscles” is never used.
