There are different cases when we add "s" to the verb.
1. Talking about the actions of present situation.
2. Talking about the third person i.e. He, She and It.
3. Talking about the possession being in present situation.
Examples:
1. John (He) goes from here.
You can see: The writer says "John (He) goes from here". So, the first case says "actions of the present situation: we have GOES in the sentence; John (He) GOES from here means John (He) is a third person singular and he passes from here. Hence, we have first two of the rules of adding "s" to the verb verified with the help of the above sentence.
2. He / she / It has black hair.
You can see: The writer is talking about all the third persons singular here. Now, there is no need to be confused as, the plural form of "have" (i.e. used for possessions) is "Has". Hence, we can say that "add "s" to the verb when any third person singular possess something being in present.
Note:
He can be John, Carlos, Nick, Obama
She can be Julia, Alina, Maria, Anna, Rose
It can be buildings, places, cats, rats, dogs, horses any animal or non living thing.
ANSWER
The answer is much simpler than that (above).
The only times you use the -s form of the verb is in present simple when you have he/she/it or a singular noun subject.
He likes ice cream. It eats anything.
The policeman walks to work. - policeman = singular noun subject.
Sees A singular verb has the form - verb + s. walk does not have + s shirts has + s but it is not a verb it is a noun. fly is a verb but it does not have + s sees is a verb it is see + s
Confidence - to be confident I am confident You are confident etc That's how to use it as a verb.
The verb form of trial is "tried." The similar verb form is "trailed" (followed).*The verb use of trial is archaic, but the spelling would be trialled.
Should is a modal verb. It has the same form for all persons and you don't use the auxiliary do in questions and negatives.You use should + the simple form of a verb to give advice.
'Choose' is a verb and therefore has no plural form. The corresponding verb is 'choice' , the plural form of which is 'choices'.
the s-form of had is a a verb
When the subject is I or a plural noun.
To make a verb plural, you typically add an "s" or "es" to the base form of the verb, depending on the verb tense and subject.
Sees A singular verb has the form - verb + s. walk does not have + s shirts has + s but it is not a verb it is a noun. fly is a verb but it does not have + s sees is a verb it is see + s
You should put "s" after the verb in the present tense when the subject of the sentence is third person singular (he, she, it) and the verb is in base form. For example, "He walks to school every day" or "She eats an apple for breakfast."
No. This situation is found in yes / no question using does. For example: She likes pomegranates. Does she like pomegranates? In the statement the verb has an -s. But in the question the do has -es so the main verb is just the base form = no -s
The noun forms of the verb to use are user, and the gerund, using.The word 'use' is also a noun form.
You use the base form of the verb. For example walk:For present simple - he/she/it and singular noun subjects add -s to the verb: he walks, it walks, the boy walksFor present simple - plural subjects use the base form of the verb: they walk, we walk, the teachers walkFor present continuous form the present participle by adding -ing to the base form ( for all subjects) and use the appropriate be verb:I am walking, she is walking, they are walking, the teachers are walking
Yes, the form "Have you tea?" is technically correct but not a good modern form. The use of to have is seen in the modern form "Do you have tea?" -- This is the interrogative form of "you do have tea" as opposed to "you have tea."In this case "to have" is the verb and "do" is the auxiliary verb form, although similar in use to the modal verbs such as can.
The base form of the verb is just the verb no -s no -ing no -ed.Walk is the base form not walks walked or walking.The -s form is the base verb + -s egwalks listens eatsFor some verbs you add -es:watches kisses matches.The -s form of the verb is used with he/she/it and singular noun subjects:He walks to school. She likes ice cream. It eats anything.The policeman walks to work - policeman = singular noun subject.
