Verb Conjugation–Grammar Rules

Verb conjugation refers to how a verb changes to show a different person, tense, number or mood.

To be verb conjugation

In English, we have six different persons: first person singular (I), second person singular (you), third person singular (he/she/it/one), first person plural (we), second person plural (you), and third person plural (they). We must conjugate a verb for each person. The verb to be is a particularly notable verb for conjugation because it’s irregular.

Verb tense conjugation

Verbs are also conjugated according to their tenses. Verb tense indicates when the action in a sentence is happening (e.g., in the present, future, or past). Regular verbs follow a standard pattern when conjugated according to tense. Look at the examples below:

Conjugation of the regular verb to live (based on tense):

Simple Present	Simple Past	Simple Future
live	lived	will live
Present Continuous	Past Continuous	Future Continuous
am living	was living	will be living
Present Perfect	Past Perfect	Future Perfect
have lived	had lived	will have lived
Present Perfect Continuous	Past Perfect Continuous	Future Perfect Continuous
have been living	had been living	will have been living

Conjugation of the regular verb to work (based on tense):

Simple Present	Simple Past	Simple Future
work	worked	will work
Present Continuous	Past Continuous	Future Continuous
am working	was working	will be working
Present Perfect	Past Perfect	Future Perfect
have worked	had worked	will have worked
Present Perfect Continuous	Past Perfect Continuous	Future Perfect Continuous
have been working	had been working	will have been working

Irregular verbs do not follow a standard pattern when conjugated according to verb tense. The following example illustrates this point:

Conjugation of the irregular verb to drink (based on tense):

Simple Present	Simple Past	Simple Future
eat	ate	will eat
Present Continuous	Past Continuous	Future Continuous
am eating	was eating	will be eating
Present Perfect	Past Perfect	Future Perfect
have eaten	had eaten	will have eaten
Present Perfect Continuous	Past Perfect Continuous	Future Perfect Continuous
have been eating	had been eating	will have been eating
Simple Present	Simple Past	Simple Future

Present Continuous	Past Continuous	Future Continuous
am drinking	was drinking	will be drinking
