Plurals of nouns-------------------------------------
Most nouns make their plurals by simply adding –s to the end (e.g. cat/cats, book/books, journey/journeys). Some do change their endings, though. The main types of noun that do this are:
Nouns ending in -y
If the noun ends with a consonant plus -y, make the plural by changing -y to -ies: singular | plural | berry | Berries | activity | Activities | daisy | Daisies |
Nouns ending in -ch, -s, -sh, -x, or -z
If the noun ends with -ch, -s, -sh, -x, or -z, add -es to form the plural: singular | Plural | church | Churches | bus | Buses | fox | Foxes | There’s one exception to this rule. If the -ch ending is pronounced with a ‘k’ sound, you add -s rather than -es: singular | plural | stomach | stomachs | epoch | epochs |
Nouns ending in -f or -fe
With nouns that end in a consonant or a single vowel plus -f or -fe, change the -f or -fe to -ves: singular | plural | knife | knives | half | halves |
Nouns ending in -o
Nouns ending in -o can add either -s or -es in the plural, and some can be spelled either way. * As a general rule, most nouns ending in -o add -s to make the plural: singular | plural | solo | solos | zero | zeros | avocado | avocados | * Those which have a vowel before the final -o always just add -s: singular | plural | studio | studios | zoo | zoos | embryo | embryos |

* Here’s a list of the most common nouns ending in -o that are always spelled with -es in the plural: singular | plural | buffalo | buffaloes | domino | dominoes | torpedo | torpedoes | echo | echoes | veto | vetoes | embargo | embargoes | hero | heroes | potato | potatoes | mosquito | mosquitoes | tomato | tomatoes | singular | plural | banjo | banjos or banjoes | cargo | cargos or cargoes | flamingo | flamingos or flamingoes | fresco | frescos or frescoes | ghetto | ghettos or ghettoes | halo | halos or haloes | mango | mangos or
