Verb - Tense - 1

 In English verb specifies 

  1. Action 
  2. condition
  3. possession 
condition -- state 
In english with out verb no verb exists. 
 
The word verb is taken from the latin word verbum which means life of language 

Without verb there is no sentence in english 

Verb denotes an action / condition/ possession of the subject 

Ex: 
  1.  I am a teacher  state 
  2. i teach english action 
  3. I have two children possession 

Types of verbs : 

1. Transitive Veb 
2. Intransitive Verb 

1. Transitive Verb : 

    If the verb has object 

    eg:  Mr. Reddy teaches English 
            Sita likes mangos 
            I met my friend 

A verb which has an object is called a transitive verb. 

To identify whether object is there or not we question with what or whom ? 


2. Intranstive Verb 

  A verb which has no object is called intranstive verb 

Ex: 
1. The bell rang loudly 
2. The sun rises in the east. 
3. I go for a walk daily. 
verb has no object. 

VERBS - FINITE AND NON FINITE 
1.  I want to eat an apple 
2. She wants to eat an apple 


if verb changes - Finite 

Finite verb; 
A verb which has subject , shows tense and number is called a finite verb 

Non Finite verb; 
A verb which has no subject , and does not show tense and number is called a non finite verb 

1. I want to eat an apple 
2. She wants to eat an apple 
3. He wanted to eat an apple 

here want verb changes so finite , to eat doesn't change NON finite 

1. I like swimming 
2. He likes swimming 
3. She liked swimming 

here like verb changes so finite, to eat doesn't change non finite.
