  • This chapter is about the irregular verbs in English. The English irregular verbs all have their own form in the past tense and their past participle is formed differently.  

    What is an irregular verb in English?

    Irregular verbs in English do not follow the same rules for the conjugation as the regular verbs. Each irregular verb has its own form in the past simple and past participle

    Irregular verbs in present tense

    The irregular verbs are conjugated the same as the regular verbs. 

    Only the 3rd person singular changes from the basic form of a regular verb in the present simple tense. The table below shows you these rules. 

    Rules for 3rd person singular Example

    Most regular verbs just add '-s' to the root of the verb for the 3rd person singular. 

    • He comes to the office.
    • The table costs 100 Euros. 
    Verbs that end with a vowel other than 'e' get a '-es'. 
    • He goes to the supermarket. 
    • She does her homework. 
    Verbs that end with '-s', '-ch', '-sh', '-x', and '-z' get a '-es'.
    • He teaches her math. 
    • She mixes the fruits. 
    Verbs that end in consonant and '-y' changes to 'ies'. 
    • She studies Spanish. 
    • He clarifies the situation. 
    Verbs that end in vowel and '-y' gets '-s'. 
    • He plays the piano. 
    • She says she will come tonight. 

    enlightenedNote that the examples contain regular and irregular verbs. 

    The verbs 'to have' and 'to be' both have a different conjugation in the present tense.
