The Spelling Rules for Adding Suffixes:

What happens to words ending in -f?

To make most words plural you normally just add s or es:

car > cars train > trains bus > buses coach > coaches

As you saw on page 12, some words ending in y need to change:

baby > babies puppy > puppies story > stories

Teaching point - learning to spell Some words ending in f must change to ve before the s:

English spelling
calf calves
half halves
leaf leaves
loaf loaves
knife knives
life lives
sheaf sheaves
shelf shelves
thief thieves
wife wives
wolf wolves
yourself yourselves

Not all words ending in -f follow this rule. Some stay the same:

chiefs beliefs roofs proofs

...and all words ending in -ff stay the same:

cliffs muffs tiffs skiffs

And a few words can be spelled both ways (English is a strange language! ) :

English spelling
dwarf dwarfs or dwarves
hoof hoofs or hooves
scarf scarfs or scarves
wharf wharfs or wharves
handkerchief handkerchiefs or handkerchieves
