What Is the Plural of Leaf?

When a color-changing leaf first falls from a tree in autumn, it represents a beautiful reminder of the cycles inherent in nature. It’s also a sign that many more soon may fall and you should probably find a rake.

As you gather one leaf after another, what word do you use to identify the growing number? In other words, what is the plural of leaf?

We’ll answer that question and explain the logic behind it. That way, you’ll know both the rule about pluralizing leaf and the grammatical principles behind it.

The Plural Version of the Word Leaf

The plural of leaf is leaves.

Although many English words can change from singular to plural by simply adding an “s” to the end, some follow nonstandard conventions. In many cases, the differences concern spelling or pronunciation. This is particularly true for words ending in “f” or “fe.”

For example, consider the following:

Leaf becomes leaves.

Knife becomes knives.

Scarf becomes scarves.

In these cases, it’s easy to understand why each word’s pluralized version would change. The incorrect versions—leafs, knifes, and scarfs—are more difficult to enunciate because the transition from “f” to “s” is softer. We change the plural endings to “ves” to make the words more distinguished and clear.

At the same time, this treatment has exceptions. There are words ending with “f” or “fe” that are pluralized with just an “s”:

Giraffe becomes giraffes.

Roof becomes roofs.

Sheriff becomes sheriffs.

Why don’t we have the words giraves, rooves, and sherrives? In cases such as these, the reason once again comes down to effective enunciation. The plurals of these words sound clearer with the softer transition from singular to plural.

How to Learn Unusual Pluralization Rules in American English

Our modern language is still always growing and changing even as it has borrowed and secured words from many different roots and languages. That makes our writing and speaking patterns dynamic, but it can also make them a little more tricky to master.

The best way to enhance your writing, proofing, and editing skills is to simply follow guidelines such as those we’ve discussed and then put the principles into practice. For example, you could write five sentences using the singular leaf and then another five using the plural leaves. If you make such a practice a habit, you’ll sense improvement in your spelling and grammar, even if it’s just a few minutes a day.
