The past tense is a verb tense expressing action, activity, state or being in the past of the current moment (in an absolute tense system), or prior to some other event, whether that is past, present, or future (in a relative tense system).

1. Preterite (or simple past)
2. Present perfect (see perfect tense)

Each of these may also be found in the progressive (continuous) aspect.

Simple past is formed for regular verbs by adding –ed to the root of a word. Example: He walked to the store. A negation is produced by adding did not and the verb in its infinitive form. Example: He did not walk to the store. Question sentences are started with did as in Did he walk to the store?

Simple past is used for describing acts that have already been concluded and whose exact time of occurrence is known. Furthermore, simple past is used for retelling successive events. That is why it is commonly used in storytelling.

Past progressive is formed by using the adequate form of to be and the verb's present participle: He was going to church. By inserting not before the main verb a negation is achieved. Example: He was not going to church. A question is formed by prefixing the adequate form of to be as in Was he going?.

Past progressive is used for describing events that were in the process of occurring when a new event happened. The already occurring event is presented in past progressive, the new one in simple past. Example: We were sitting in the garden when the thunderstorm started. Use is similar to other languages' imperfect tense.

Present perfect simple is formed by combining have/has with the main verb's past participle form: I have arrived. A negation is produced by inserting not after have/has: I have not arrived. Questions in present perfect are formulated by starting a sentence with have/has: Has she arrived?

Present perfect simple is used for describing a past action's effect on the present: He has arrived. Now he is here. This holds true for events that have just been secluded as well as for events that have not yet occurred.

Present perfect progressive is formed by prefixing have/has before the grammatical particle been and the verb's present participle form: We have been waiting. A negation is expressed by including not between have/has and been: They have not been eating. As with present perfect simple, for forming a question, have/has is put at the beginning of a sentence: Have they been eating?

Present perfect progressive is used for describing an event that has been going on until the present and may be continued in the future. It also puts emphasis on how an event has occurred. Very often since and for mark the use of present perfect progressive: I have been waiting for five hours / I have been waiting since three o'clock.
