The verb is the most important part of the sentence parts , because it shows the time of the action in the sentence.

Generally the verb in English has three types called "conjugations" , and they are used in the different forms forming the verbs in it's various tenses , and they are :

• present > first conjugation

• Watch / Watched / watched
• Tell / Told / Told
• Play / Played / Played
• Read / Read / Read
