Past
The past is the set of all events that occurred before a given point in time. The past is contrasted with and defined by the present and the future. The concept of the past is derived from the linear fashion in which human observers experience time, and is accessed through memory and recollection. In addition, human beings have recorded the past since the advent of written language. The first known use of the word "past" was in the fourteenth century; it developed as the past participle of the middle English verb ''passen'' meaning "to pass." Grammar In grammar, actions are classified according to one of the following twelve verb tenses: past (past, past continuous, past perfect, or past perfect continuous), present (present, present continuous, present perfect, or present perfect continuous), or future (future, future continuous, future perfect, or future perfect continuous). The past tense refers to actions that have already happened. For example, "she is walking" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Past Perfect
The pluperfect (shortening of plusquamperfect), usually called past perfect in English, is a type of verb form, generally treated as a grammatical tense in certain languages, relating to an action that occurred prior to an aforementioned time in the past. Examples in English are: "we ''had'' arrived"; "they ''had'' written". The word derives from the Latin ''plus quam perfectum'', "more than perfect". The word "perfect" in this sense means "completed"; it contrasts with the "imperfect", which denotes uncompleted actions or states. In English grammar, the pluperfect (e.g. "had written") is now usually called the past perfect, since it combines past tense with perfect aspect. (The same term is sometimes used in relation to the grammar of other languages.) English also has a ''past perfect progressive'' (or ''past perfect continuous'') form: "had been writing". Meaning of the pluperfect The pluperfect is traditionally described as a tense; in modern linguistic terminology it may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Past Participle
In linguistics, a participle () (from Latin ' a "sharing, partaking") is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, ''participle'' has been defined as "a word derived from a verb and used as an adjective, as in a ''laughing face''". “Participle” is a traditional grammatical term from Greek and Latin that is widely used for corresponding verb forms in European languages and analogous forms in Sanskrit and Arabic grammar. Cross-linguistically, participles may have a range of functions apart from adjectival modification. In European and Indian languages, the past participle is used to form the passive voice. In English, participles are also associated with periphrastic verb forms (continuous and perfect) and are widely used in adverbial clauses. In non-Indo-European languages, ‘participle’ has been applied to forms that are alternatively regarded as converbs (see Sireniki Eskimo below), gerunds, g ...

Time
Time is the continued sequence of existence and event (philosophy), events that occurs in an apparently irreversible process, irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantification (science), quantify derivative, rates of change of physical quantity, quantities in scientific realism, material reality or in the consciousness, conscious qualia, experience. Time is often referred to as a fourth dimension, along with Three-dimensional space, three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circular definition, circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate som ...

Future Perfect
The future perfect is a verb form or construction used to describe an event that is expected or planned to happen before a time of reference in the future, such as ''will have finished'' in the English sentence "I will have finished by tomorrow." It is a grammatical combination of the future tense, or other marking of future time, and the perfect, a grammatical aspect that views an event as prior and completed. English In English, the future perfect construction consists of a future construction such as the auxiliary verb ''will'' (or ''shall'') or the going-to future and the perfect infinitive of the main verb (which consists of the infinitive of the auxiliary verb ''have'' and the past participle of the main verb). This parallels the construction of the "normal" future verb forms combining the same first components with the plain infinitive (e.g. ''She will fall'' / ''She is going to fall''). For example: * She will have fallen asleep by the time we get home. * I shall ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Present Perfect
The present perfect is a grammatical combination of the present tense and perfect aspect that is used to express a past event that has present consequences. The term is used particularly in the context of English grammar to refer to forms like "I have finished". The forms are ''present'' because they use the present tense of the auxiliary verb ''have'', and ''perfect'' because they use that auxiliary in combination with the past participle of the main verb. (Other perfect constructions also exist, such as the past perfect: "I had eaten.") Analogous forms are found in some other languages, and they may also be described as present perfect; they often have other names such as the German ''Perfekt'', the French ''passé composé'' and the Italian ''passato prossimo''. They may also have different ranges of usage: in all three of the languages just mentioned, the forms in question serve as a general past tense, at least for completed actions. In English, completed actions in many c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Future
The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone. In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be. Religious figures such as prophets and diviners have claimed to see in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Present
The present (or here'' and ''now) is the time that is associated with the events perceived directly and in the first time, not as a recollection (perceived more than once) or a speculation (predicted, hypothesis, uncertain). It is a period of time between the past and the future, and can vary in meaning from being an instant to a day or longer. It is sometimes represented as a hyperplane in space-time, typically called "now", although modern physics demonstrates that such a hyperplane cannot be defined uniquely for observers in relative motion. The present may also be viewed as a duration (see '' specious present'').James, W. (1893)The principles of psychology New York: H. Holt and Company. Page 609.
