Why Is There Confusion over the Plural of Calf?

There is confusion because the rule for forming the plurals of nouns ending f isn't straightforward. Most nouns will drop the f and gain a ves. For example:
  • Loaf becomes loaves.
  • Leaf becomes leaves.
Some just add s. For example:
  • Roof becomes roofs.
  • Chief becomes chiefs.
With some words, both versions are accepted. For example:
  • Scarf becomes scarfs or scarves.
  • Dwarf becomes dwarfs or dwarves.
The plural is always calves. Unfortunately, there is no clever way of knowing which nouns ending f follow which rules. You have to know. (For example, you have to know that gulf becomes gulfs, but calf becomes calves.)
