The subject and the verb in the English sentence must match
Example
1.We Go to the Beach on Saturdays
The word "we" is a plural subject, so it uses the plural form of the verb.
2.He Goes to the Beach on Saturdays
The word "he" is a Singular subject so it uses the Singular form of the verb.If the subject is Plural like we, they use the plural form of the verb as well and if the subject is Singular like he, she then use the singular form of the verb.
Singular and Plural Nouns
When using the subject Plural do not add s to the verb
Example
1.The Cars Look expensive
The word "cars" is nouns plural,while the word "look" is a verb, because the subject is plural, the verb does not need to be added s.
2.The Car Looks Expensive
The word "car" is a singular noun (singular), while the word "looks" is a verb, because the subject is single, the verb needs to be added S.
 
In Singular and Plural Nouns there are several rules1.Subject Singular namely he, she and it2.Subject l and You even though it is a Singular Noun form but uses the plural / plural form in the verb.
Example
1.l Like to Go Swimming
2.She Likes to  Go Swimming
The difference between the two sentences lies in the verb used.
 
Auxiliary Verb
Auxiliary Verb is an additional verb in a sentence such as do / does in the simple present or am, is, are, was, were in the continuous tense or have / has in the perfect tense.
Example
1.The Dogs donΓÇÖt want it
2,The Dog doesnΓÇÖt want it
3.We are Going to the Beach
4.He is Going to the Beach
5.Anna and Tony have been Driving for Hours
6.Anna has been Driving for Hours
 
Modal Verbs
-May
-Could
-Will
- Must
-Should
The verb is included in Auxiiary Verbs because it helps the main verb in a sentence, but the subject and verb rules are different.Verbs followed by a modal verb do not use the s / es verb form, always use the infinitive form.
Example
1.My Friends Might Come (True)
2.My Friend Might Comes (False)
3.You Should Come (True)
4.He Should Comes (False)
 
Indefinitve Pronoun
-Everbody
-Nobody
-Anybody
-Someone
The pronoun uses the singular form of the verb.
Example
1.Everbody Wants to be Loved
2.Nobody Likes to be Left Out
 
Compound Subject
Compund Subject is a combination of Nouns and relative clauses.
Example
1.My Mum is Happy for Me
2.My Mum and Dad are Proud of Me
In the second sentence, the singular subject is combined with the word "and" which means the subject becomes plural.
My Mum and Dad -> They
-They are Proud of Me
2 or more single subjects combined with ΓÇ£andΓÇ¥ are the plural subjects and require a plural verb.
 
Subject and Subject
                +
Plural Verb
Example
-Peter or Paul is Coming
Two single subjects in the sentence are considered single subjects because the word "or" is given as an option, and does not say both.
Example
1.Peter and Paul are Coming
2.Playing Football is Fun
For the Gerunds V + ing and the gerund phrase, when the gerunds is the subject it must use the singular form of the verb.
Example
1.Waiting for the Bus is Annoying
When a sentence is combined with the word "and" it keeps using the plural form.
Example
1.Meeting Friends After Work and Going to the Beach are My Favourite things about Living Here
 
Group Nouns
Group Nouns are compound nouns.
-Club
-Tim
-Company
-Family
-Crowd
-Class
The noun is the singular form of a combination of people / things. Nouns can be a singular / plural form
depending on the meaning / meaning of each sentence. Because it can describe an individual in a group and as long as more than one is sure to be plural. But it is possible to use several nouns be a single unit when referring to the whole group then it is singular.
Example
1.The Team is Organising the Event
The word "the team" is a singular noun because it refers to a single unit so it is necessary to use the singular verb "is".
2.The Team are Meeting Today
The sentence uses the plural form of the verb.
3. The Teams are Meeting Today
When using the plural form of the verb it means that there are many group and individual nouns. They comprise more than one team / club.
 
There are some nouns that look like plural nouns but use the singular.
Example
1.The News
The sentence looks like the plural because there is an S so it needs a single verb to interpret the sentence as the singular form.
-The News is Interesting
2.The Furnitures are Comfortable (False)
3. The Furnitures is Comfortable (True)
Likewise, the noun that cannot be counted (Uncountable) is treated like this too.
 
The subject and the verb always change positions, the subject does not always come before the noun. In English questions it is necessary to identify which one is the subject before choosing the form of the verb.
Example
1.What are the Steps we need to Follow
In the sentence "the steps" is the subject while the verb is "are" because the sentence is a plural verb.
2.There are Many Plants in your Garden
3.There is a Plant in the Bathroom
4.The Car,Which Belongs to My Brother is not Very Clean
5.The New Features of the car are Impressive
