Verbs

Verb is a word that describe an action (like "run") a state (like "be"), or an event (like "happen"). Verbs tells us what the subject of the sentence is doing or what condition it is in. For instance, in the sentence "She sings", the verb "sings" tells us what the subject (She) is doing. 

Verbs can also indicate time. For example, in "He walked", the verb "walked" tells us not only the action but also that it happened in the past. 

Verbs are the central element in sentences. Most of thing we say are build around them. English verbs have up to five one-word form ( except be, which has eight).

• The base form: the one found in dictionaries, for example go, write, play. This is used for present tenses forms after I, we, you (singular and plural) and they, in infinitives, and in imperatives.
• The third person singular present: for example goes, writes, plays. 
• The past tense: for example, went, wrote, played.
• The past participle: for example, gone, written, playing. Note that in regular verbs the past participle is the as the past tense.
• The ing form: for example going, writting, playing. Depending on how it is used, the ing form may be called a "Present participle" or a gerund. Verbs form which show time (e.g. Goes, went) are often called finite in grammer; Other forms (e.g. Written, playing) are non-finite.

Tenses

Tenses are verbs forms that show the time of action and situations, either as single words or including auxiliary verbs. 

We went home - (simple past tense) 

Have you written to Jaime? -( Present perfect tense.) 

Auxiliaries verbs

Auxiliary (helping) verb are used with Other verbs to add various kind of meaning. Be, have and do help to make progressive (or continuous) and perfect estructures, questions and negative. 

Modal auxiliaries verbs (Must, can, could, will, would, may, might, shall, Should, and Ought) are used with verbs to add ideas such as futurity, certainty, probability, obligation, and permission. 

What can following a verb? 

Different non-auxiliary verbs can be followed by different kind of word and estructures. This is partly a matter of meaning: after a verb like eat or break, for instance, it is normal to expect a noun: after try or stop, it is natural to expect a verb. 

It is also partly a matter of grammatical rules that have nothing to do with meaning. Before an object, wait is followed by for; expect has no Preposition. 

Active verb tense

Present, future, and past; simple progressive and perfect. 

English verbs can refer to present future or past time. 

• Present: I am watching you
• Future: she will see you tomorrow
• Past: who said that? 

For each kind of time, there are three possibilities with most verbs: simple; progressive or continuous (be + being);

and perfect (have + past participle). 

• Simple Present: I start
• Present progressive: I am starting
• Present perfect: I have started

Some grammer use the word "tense" only for simple forms like goes or went; for form like is going or has gone they prefer to talk about progressive or perfect "aspect", and they say that english has no future tense. This are principally questions of  terminology, not grammatical fact, and have no pratical importance. I practical english the term "tense" is used for all verb forms and structures that indicate time. 

Tense and time 

There is not a direct relationship between verbs forms and time. For example, a past verb like went is not only used to talk about past event (e.g. We went to morroco last january), but also about unreal or uncertain present or future events (e.g. It would be batter if we went home now). 

And present or future verbs can be used to talk about the future (e.g. I'm seeing Daniel tomorrow) also, progressive and perfect form express ideas that are not simple concerned with time - for example continuatio, present importance. 

The importance of verbs 

Mastering the use of verb is assential for anyone learning. Since verbs are the core of sentences, using them correctly us key to effective communitions. Verbs help us express when something happens and what is happening, whether it is a past event, a currently action, or a future possibility.

Conclusion

In summary, verbs are one of the most crucial element of English grammar. They allow us to convey actions, state and events, making them indispensable for clear communitions. By understanding the different types of verbs and how to use them learners can enhance their speaking and writting skills in english.
