Irregular Plural Nouns: -f/-fe and –ves

Here are two tables illustrating common examples of irregular plural nouns following the -f/-fe to -ves rule, as well as exceptions to the rule:

Singular (ending in -f)Plural (ending in -ves)
Singular (exceptions)Plural (exceptions)

Patterns to Recognize:

  • If a noun ends in -f or -fe, it often changes to -ves in the plural form.
  • Words where the -f or -fe is preceded by a vowel often just add -s (e.g., chiefs, safes).

Notably, even within the -ves rule, some irregularities occur, such as:

  • sheriff becomes sheriffs
  • dwarf can become dwarfs or dwarves, the latter particularly in fantasy contexts.

In addition to these tables, it’s useful to remember a few bullet points when dealing with these nouns:

  • The shift from -f/-fe to -ves often alters the pronunciation, stressing the final syllable.
  • Some nouns retain their -f/-fe endings and simply add -s; context and usage can influence the accepted plural form.

Origin of the Word Calf

The term calf has a rich etymological background rooted in various languages. The word for the young of the domestic cow, as well as other mammals like bison, traces back to the Old English cealf. This in turn came from Proto-Germanic *kalbam, a word with no known further ancestry. As languages evolved, so did the term, morphing into Middle English as calf.

The word’s usage isn’t limited to livestock alone; it also describes the fleshy part of the back of the lower human leg. While the origin of this particular meaning is not crystal clear, some linguists suggest that it could come from the Old Norse word kalfi, indicating it may be from the same Germanic root as the term for the young bovine.

Below are two tables that provide a glance at the word’s development over time:
