Why Is There Confusion over the Plural of Life?

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.
Leaf becomes leaves.

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 life is always lives. Unfortunately, there is no clever way of knowing which nouns ending f or fe follow which rules. You have to know.
