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.)
