what is root form of verb ?
Traditionally, the base form of the verb consists of the infinitive such as eat, sleep, buy, wear, etc. without adding 'to'. It is free from agreement, tense, or participle endings. It is the simplest form of verb, the way it is found in the dictionary. The first- and second-person singular, and the plural present-tense form of a verb is called a base verb. Instances of the same are: make, excel, cry, try, pray, check, etc.
