In grammar, tense is a category that expresses time reference. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns.
In linguistics, aspect is a grammatical category that expresses how a verbal action, event, or state, extends over time. For instance, perfective aspect is used in referring to an event conceived as bounded and unitary, without reference to any flow of time during the event. Imperfective aspect is used for situations conceived as existing continuously or habitually as time flows.
The preterite or preterit is a grammatical tense or verb form serving to denote events that took place or were completed in the past; in some languages, such as Spanish, French, and English, it is equivalent to the simple past tense. In general, it combines the perfective aspect with the past tense and may thus also be termed the perfective past. In grammars of particular languages the preterite is sometimes called the past historic, or the aorist. When the term "preterite" is used in relation to specific languages, it may not correspond precisely to this definition. In English it can be used to refer to the simple past verb form, which sometimes expresses perfective aspect. The case of German is similar: the Präteritum is the simple (non-compound) past tense, which does not always imply perfective aspect, and is anyway often replaced by the Perfekt even in perfective past meanings.
The subjunctive is a grammatical mood, a feature of an utterance that indicates the speaker's attitude toward it. Subjunctive forms of verbs are typically used to express various states of unreality such as wish, emotion, possibility, judgment, opinion, obligation, or action that has not yet occurred; the precise situations in which they are used vary from language to language. The subjunctive is one of the irrealis moods, which refer to what is not necessarily real. It is often contrasted with the indicative, a realis mood which principally indicates that something is a statement of fact.
The verbal morphology of Armenian is complicated by the existence of two main dialects, Eastern and Western. The following sketch will be a comparative look at both dialects.
In grammar, a future tense is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French achètera, meaning "will buy", derived from the verb acheter. The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration.
Spanish verbs form one of the more complex areas of Spanish grammar. Spanish is a relatively synthetic language with a moderate to high degree of inflection, which shows up mostly in Spanish conjugation.
The perfect tense or aspect is a verb form that indicates that an action or circumstance occurred earlier than the time under consideration, often focusing attention on the resulting state rather than on the occurrence itself. An example of a perfect construction is I have made dinner. Although this gives information about a prior action, the focus is likely to be on the present consequences of that action. The word perfect in this sense means "completed".
The continuous and progressive aspects are grammatical aspects that express incomplete action or state in progress at a specific time: they are non-habitual, imperfective aspects.
The imperfect is a verb form that combines past tense and imperfective aspect. It can have meanings similar to the English "was walking" or "used to walk". It contrasts with preterite forms, which refer to a single completed event in the past.
The perfective aspect, sometimes called the aoristic aspect, is a grammatical aspect that describes an action viewed as a simple whole, i.e., a unit without interior composition. The perfective aspect is distinguished from the imperfective aspect, which presents an event as having internal structure. The term perfective should be distinguished from perfect.
The Germanic language family is one of the language groups that resulted from the breakup of Proto-Indo-European (PIE). It in turn divided into North, West and East Germanic groups, and ultimately produced a large group of mediaeval and modern languages, most importantly: Danish, Norwegian, and Swedish (North); English, Dutch and German (West); and Gothic.
Proto-Indo-European verbs reflect a complex system of morphology, more complicated than the substantive, with verbs categorized according to their aspect, using multiple grammatical moods and voices, and being conjugated according to person, number and tense. In addition to finite forms thus formed, non-finite forms such as participles are also extensively used.
The pluperfect, usually called past perfect in English, characterizes certain verb forms and grammatical tenses involving an action from an antecedent point in time. Examples in English are: "we had arrived" before the game began; "they had been writing" when the bell rang.
A feature common to all Indo-European languages is the presence of a verb corresponding to the English verb to be.
In French grammar, verbs are a part of speech. Each verb lexeme has a collection of finite and non-finite forms in its conjugation scheme.
Tense–aspect–mood or tense–modality–aspect is an important group of grammatical categories, which are marked in different ways by different languages.
This article discusses the conjugation of verbs in a number of varieties of Catalan-Valencian, including Old Catalan. Each verbal form is accompanied by its phonetic transcription. Widely used dialectal forms are included, even if they are not considered standard in either of the written norms: those of the Institut d'Estudis Catalans and the Acadèmia Valenciana de la Llengua. Other dialectal forms exist, including those characteristic of minor dialects such as Ribagorçan and Algherese and transitional forms of major dialects.

Portuguese verbs display a high degree of inflection. A typical regular verb has over fifty different forms, expressing up to six different grammatical tenses and three moods. Two forms are peculiar to Portuguese within the Romance languages:
