Everyday Grammar: Unusual Plurals3 英语日常语法:不寻常的复数

One fish, two fish, red fish, blue fish, goes the Dr. Seuss children’s story. Why isn’t it two fishes? You may think, “Ok, it’s hard to count fish so we group them all together. No problem.”

Life on the farm

It’s easy to understand that farmers would not worry about making plurals when they talk about sheep. After all, they are almost always in a group. When you have one sheep, you can also call it a ram1 or a ewe, and make those nouns plural2 by adding an –s: rams4 and ewes.

Let’s look at some other things we can make plural. You’ve got a left foot and a right foot. Put them together and what have you got? Two feet. That doesn’t follow the “add an –s” rule.

Same with mouse and its plural, mice. What happened to our neat rule for making words plural?

The German influence

The answer is in our history. English came from German roots. German grammar changes the vowel5 sound in the middle of the word to show it is plural. The plural form of the German word for goose, Gans is G?nse. The vowel with two dots over it is called an umlaut. So goose becomes geese in English.

There are other plurals where the vowel changes like in the German pattern. Man – men and woman – women are examples of different vowel sounds in plural words. Sometimes a consonant6 changes, as with words that end in an f sound, such as leaf. The voiceless sound f takes on a voiced quality, or v, and an s sound is added to the word. We have autumn leaves and sharp knives.

Another way to make plurals in English is to add the suffix7 –en. We see this in the words brother – brethren; child - children and ox -oxen. These are words that come from Old English.

Words of foreign origin

With words that come from foreign languages, there are some patterns that may help you remember the plural. Many technical words in English came from Latin. Let’s look at the plural of some words from Latin. Words that end in –us- drop that ending and add -–i to become plural, as in fungus8fungi9 and cactus10cacti11.

What is that orange thing on the tree?

     It’s a fungus. There are a lot of different fungi in this forest.

For words that end in –um, the ending changes to –a, as in the words datum12 – data and medium – media. These two words are more common in their plural forms than the singular forms in our digital life. Listen to how the words medium and media appear in this conversation.

          I heard you got a job at the New York Times.

                Yeah, I’m glad to be working in mass media.

          But newspapers are a dying medium, aren’t they?

                Hey, I hope not. I’m writing a blog for them.

When a word from Latin ends in –-ex or –ix, the plural ending is –ices. This results in index – indices and matrix – matrices. Here is another conversation    

           The financial news is bad. The Dow Jones index is down.

                  Don’t worry, there are other indices, like employment, going up.

Try it yourself

Are you ready to try making plurals with some English words?

Use the Germanic pattern for these words:

       tooth (plural: teeth)

       wolf (plural: wolves)

Use the Latin pattern for these words:

       mémorandum (plural: memoranda)

       focus (plural: foci)

There are many more irregular plural forms in English. We’ll look at those in another episode of Everyday Grammar. For now, we leave you with Frank Sinatra, singing Autumn Leaves,

  But I miss you most of all my darling

  When autumn leaves start to fall
