IRREGULAR PLURAL WORDS Many nouns do NOT follow the regular pattern for adding -s or –es to show more than one (plural form). Regular: hat + s = hat s ; watch + es = watch es When words do not follow the regular pattern, we say they are IR REGULAR (ir = not). SingularPlural toothteeth childchildren

“F” CHANGES TO “VES” Most of the time, when we have a SINGULAR noun ending with the letter “f” or “f + silent e” and we change it to a PLURAL noun, we change the “f” to “ves.” Singular:Plural: wifewives leafleaves wolfwolves
