The Spelling Rules for Adding Suffixes:

What happens to words ending in -f ?

Usually, we add the suffixes -s or -es to make plurals.

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

As you saw before, some words ending in y need to change:

baby > babies puppy > puppies story > stories

Teaching point - learning to spell This is also true for some words ending in f:

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!):

 Plural

"Thank goodness for Spellzone during this remote learning phase. The site is easy for students to navigate independently and they're really enjoying the activities and spelling games. You get an awful lot for your money with Spellzone. Really reassuring is the very prompt response with helpdesk queries. I've very rarely needed the helpdesk, but when I have, the issue has been addressed and sorted within a very short time."
