Overview
The past tense signifies actions that were done in the past. Conjugating verbs to show the past tense is very easy in English, almost as easy as conjugating the present tense.
Past Tense
Regular verbs take the ending '-d' or 'ed' in the affirmative. The negative and interrogative are formed using did (past of the auxiliary verb do) together with the infinitive of the verb. The verb work is conjugated as follows: Affirmative I worked you worked he worked she worked it worked we worked you worked they worked Negative I did not work or I didn't work you did not work or you didn't work he did not work or he didn't work she did not work or she didn't work it did not work or it didn't work we did not work or we didn't work you did not work or you didn't work they did not work or they didn't work Interrogative did I work did you work did he work did she work did it work did we work did you work did they work Negative Interrogative did I not work or didn't I work did you not work or didn't you work did he not work or didn't he work did she not work or didn't she work did it not work or didn't it work did we not work or didn't we work did you not work or didn't you work did they not work or didn't they work Irregular verbs change their form in the past tense affirmative in a variety of ways. The past of go, for example, is went, of buy, bought, of keep, kept. As with the regular verbs, the negative and interrogative are formed using did together with the infinitive of the verb. The verb go is conjugated in the past tense as follows: Affirmative I went you went he went she went it went we went you went they went Negative I did not go or I didn't go you did not go or you didn't go he did not go or he didn't go she did not go or she didn't go it did not go or it didn't go we did not go or we didn't go you did not go or you didn't go they did not go or they didn't go Interrogative did I go did you go did he go did she go did it go did we go did you go did they go Negative Interrogative did I not go or didn't I go did you not go or didn't you go did he not go or didn't he go did she not go or didn't she go did it not go or didn't it go did we not go or didn't we go did you not go or didn't you go did they not go or didn't they go
