Review, Practice, and Explore – Chapter 13 • 117
Some words that end in /f/ form their plural in the “regular” way. In Chapter 4, we saw that our
regular rule of pluralization is that if a word ends in a voiceless consonant, add /s/; so, roof /ruf/ →
/rufs/. Why, then, do we have forms like wolves and scarves instead of wolfs and scarfs? Because in
Old English, the vowel before the final s was pronounced, and a phonological rule of Old English
was that when a fricative came between voiced sounds, it, too, became voiced: the plural of wulf
‘wolf’ was [wulvas] phonetically, though it would be spelled wulfas. Old English had no voiced
fricatives as phonemes, so [f, θ, s] did not have [v, ð, z] as voiced counterparts phonemically, though
they did occur as allophones quite early in Old English. Later on in the Middle English period, after
influence from French, we began to use the letter v. So our current state of pluralization of words
that end in /f/ illustrates the conflict between our natural phonological rule of pluralization and the
influence of spelling on pronunciation.
Determine the plural of each of the following words, and then look them up in a dictionary.
Determine whether any of the plurals differ for British speakers and American English speakers.
Also, determine which of them have two accepted, standard spellings:
belief, leaf, roof, scarf, cuff, wolf, loaf, dwarf, brief, cliff, reef, hoof, proof, chief, knife, half,
calf, life, thief, wharf, chef, plaintiff, wife, shelf, handkerchief, giraffe, sheriff, whiff
Answers. There could also be other variations not indicated here.
belief beliefs
leaf leaves (but Leafs in the Toronto Maple Leafs)
roof roofs (but can be pronounced as /ruvz/)
