If the word ends in a consonant-vowel-consonant pattern it gets a double consonant +EDe.g. RUB > RUBBED HOP > HOPPEDIf the word ends in a consonant-vowel-consonant pattern it gets a double consonant +INGe.g. RUB > RUBBING HOP > HOPPINGWords ending in w,x,y,z don't follow this rule, just add ED or ING e.g. snowed, snowing, boxed, boxing
It follows the standard rule: monosyllabic words ending with a single 's' or 'z' double that consonant and add 'es' to form the plural. This is the logic: if a word ends in an 's' or 'z' you cannot just add another 's' to form the plural - it would be unpronounceable. Therefore you need to add 'es'. However, if you add 'es' to a monosyllable ending in a single consonant, the 'e' will turn the vowel into a long vowel. Therefore you must double the final 's' or 'z' to keep the vowel sound short when you add the 'es'. If you did not double the 'z' of 'quiz' when you formed the plural, it would be pronounced 'kwy-ziz' instead of 'kwi-ziz'.
