Leaf/leaves evolved from the Old English word of the same spelling, ‘leaf.‘ Leaf was introduced to Old English and originates from the Proto-Germanic lauba, and the Proto-Germanic languages of Old Norse (lauf), Dutch (loof), Old High German, and German.
Similarly, if we take a look at the origins of other singular noun forms that are irregular and end in -f or -fe, they all derive from the Proto-Germanic languages listed above. Wolf, elf, shelf, knife, wife, and life are all words that evolved from German, and its corresponding languages/dialects of the Proto-Indo-European languages.
Based on each of these nouns’ shared origins, it’s likely that the Germanic languages recognized more than one possible endings for plural noun forms than the standard -s or -es. Consider the I-mutation, which is also a Germanic language pattern, and involves “the raising and fronting of a root vowel in anticipation of “i” or “y” sound in a suffix.”
Just like the singular nouns that end in -f or -fe, these plural noun forms are all modified from singular to plural by replacing the root vowels with another pair of vowels: goose switches to geese as a plural; tooth = teeth; and foot = feet. These are all effects of the I-umlaut, and is a notably Germanic way of modifying a singular noun to its plural, albeit irregular noun form.
