NOUNS are 'people, places and things'. VERBS are 'doing' or 'action' words. Many words are used either as a noun or verb to mean two different things.

An example is clearer than the definition. Ex. If you look the words 'book' and 'study' up in a dictionary you will see something like this:
'book (v)' .....and 'book (n) '......

'study (v)'..... and 'study (n) '......

The (v) is the verb form and is the 'action' of booking (a ticket), the (n) is the 'thing' called 'book', something that is read.

Study (v) is the action of studying, the (n) means the 'thing' called 'study' (a room in a house).

One more?:
'fish (v)'..... and 'fish (n)'..... The verb (which must be put in the right tense and person) is the action of fishing. The noun (which must be in either the singular or plural form) is the thing you catch and eat.

Are you sure you understand the difference between nouns and verbs?
NOUNS are 'people, places and things'. VERBS are 'doing' or 'action' words.

The Conjugation Of Verbs
Just as with NOUNS, the form and spelling of the VERB can, sometimes must, change.

There are six forms in each of the tenses; three singular and three plural. You should always know which form you are using. (e.g.. 1st person singular, 3rd person plural etc.)

Verbs are best learned with the appropriate subject pronoun. We call this the 'conjugation' of the verb. The verb and its subject noun ('people, places, things') and subject pronouns ('I, you, he,she, it, we, they') must always be in AGREEMENT.

A pronoun is simply a word that is used instead of a noun. Personal Pronouns differ according to whether they are the Subject or the Object of the verb.

The Subject is the person or thing creating the 'action'. The Object is the 'person, place or thing' on the receiving end!

First, we will learn the Subject forms, then the Object forms.
Personal Pronouns - Subject Form

Singular:
1st person(1ps) - I (meaning the person speaking)
2nd person (2ps) - you (meaning the person spoken to)
3rd person(3ps) - he (one male person), she (one female person), it (a singular neuter noun)

Plural:
1st person(1pp) - we (meaning the speaker and someone else)
2nd person(2pp) - you (meaning the people (more than one person) spoken to)
3rd person(3pp) - they (meaning more than one person or thing)

One uses the first person when one is speaking; singular if talking only about oneself, plural if talking about oneself and one other person or more.
Ex.

1ps I build a web site

1pp We (you and I) go to Ubon

One uses the second person when one is speaking about the listener; singular if talking only about them, plural if talking about them and one other person or more. Fortunately the second person singular and plural are the same so no worries here!

Ex.

2ps You cook supper

2pp You (your sister and you) eat supper

One uses the third person when one is speaking about a noun; singular if the noun is singular, plural if the noun is plural.
Ex.

3ps The child reads

3pp The children read

Types Of Verbs

Continuous Verbs

The first group, called "Continuous Verbs", contains most English verbs. These verbs are usually physical actions which you can see somebody doing. These verbs can be used in all tenses.
Examples: to run, to walk, to eat, to fly, to go, to say, to touch etc.

Non-continuous Verbs
The second group, called "Non-continuous Verbs", is smaller. These verbs are usually things you cannot see somebody doing. These verbs are rarely used in "continuous" tenses. They include:

Abstract Verbs:

to be, to want, to cost, to seem, to need, to care, to contain, to owe, to exist...
Possession Verbs: to possess, to own, to belong...
Emotion Verbs: to like, to love, to hate, to dislike, to fear, to envy, to mind...

Examples:
He is here now He is being here now
He wants a drink now He is wanting a drink now

Mixed Verbs
The third group, called "Mixed Verbs", is the smallest group. These verbs have more than one meaning. Some meanings behave like "Non-continuous Verbs", while other meanings behave like "Continuous Verbs."

Examples: to have, to appear, to see, to hear, to feel, to weigh, to look ...
