Why Is There Confusion over the Plural of Leaf?

There is confusion because the rule for forming plurals with nouns ending in "f" or "fe" isn't straightforward. Most nouns will drop the "f" or "fe" and gain a "ves." For example:

• "Knife" becomes "knives."
• "Loaf" becomes "loaves."

Some just add s. For example:

• "Safe" becomes "safes."
• "Chief" becomes "chiefs."

With some words, both versions are accepted. For example:

• "Scarf" becomes "scarfs" or "scarves."
• "Dwarf" becomes "dwarfs" or "dwarves."

The plural of "leaf" is always "leaves." Unfortunately, there is no clever way of knowing which nouns ending "f" or "fe" follow which rules. You have to know. (For example, you have to know that "leaf" becomes "leaves," but "belief" becomes "beliefs.")
