Rules for changing the singular and plural nouns

1. the plural form of the vast majority of uncounting nouns is to add the suffix-S at the end of the word.
Pronunciation Change: the end is the clear consonants read [s], and the end is the Voiced Consonants or vowels read [Z].
Example: Friend → friends; CAT → cats; style → styles; sport → sports; piece → pieces

 

2. All words ending with S, Z, X, CH, and sh Add the suffix-es at the end of the word to form the plural.
Pronunciation changes: Read [iz] in a unified manner.
Example: Bus → buses; quiz → quizzes; Fox → foxes; match → matches; flash → flashes

 

3. Change "Y" to "I" and add "-es.
Pronunciation Change: Add read [Z].
Example: Candy → candies; Daisy → daisies; fairy → fairies; lady → ladies; story → stories

 

4. If a noun ending with-O is not a foreign word or abbreviation, add-es. Otherwise, add-s to form the plural.
Pronunciation Change: Add read [Z].
Example: Tomato → tomatoes; potato → potatoes; torpedo → torpedoes; bingo → bingoes
Examples: silo → silos; piano → pianos (foreign words); Photo → photos; macro → macros (acronyms)

 

5. the nouns ending with-f or-Fe mostly change-f or-Fe to-ves, with exceptions.
Pronunciation Change: The ending sound [f] is changed to [VZ].
Example: knife → knives; Life → lives; leaf → leaves; staff → staves; scscarf → scarves; inverse example: roof → Roofs

 

6. To express a specific number, use the quantifiers

Verb changes when the subject is called by three people
① In general, when the subject is a third person singular, the verb should be in the "S" type (that is, the third person singular form ).
② The composition of the so-called verb "S" type can be recorded according to the rules for changing nouns to the plural, namely:
I) add s directly at the end of the verb. For example:
Play-plays, want-wants, work-works, know-knows, help-helps, get-gets
Ii) verbs ending with letters S, X, CH, or O plus-es; for example:
Guess-guesses, fix-fixes, teach-teaches, brush-brushes, go-goes, do-does, watch-watches, catch-catches
Iii) The verb ending with a consonant letter + y first changes y to I, plus-es. For example:

Study-studies, carry-carries, fly-flies, worry-worries
