Verb terms explained

Use this quick reference when a label in a verb table is unfamiliar. Each explanation includes a Greek example.

Conjugation
The way a verb changes its endings, and a group of verbs with similar patterns. γράφω — I write; γράφεις — you write. See the groups.
Person and number
Who the verb refers to, and whether the subject is singular or plural: γράφω — I write; γράφουμε — we write.
Stem
The part of a verb to which endings are added. A verb can use different stems: γράφ- in γράφω, but γράψ- in θα γράψω.
Tense
A verb form or combination associated with time: γράφω — I write; έγραψα — I wrote; θα γράψω — I will write.
Aspect: continuous and simple
How an action is presented. Continuous shows it unfolding or recurring: έγραφα — I was writing / used to write. Simple views it as a whole: έγραψα — I wrote. The technical terms are imperfective and perfective. Perfective is not the same as the perfect tense.
Imperfect
A past form used for ongoing or repeated situations: έγραφα κάθε μέρα — I used to write every day.
Simple past (aorist)
A past form that presents an action as a whole: χθες έγραψα ένα μήνυμα — yesterday I wrote a message.
Perfect tenses
Forms relating a completed action to a reference point: έχω γράψει — I have written; είχα γράψει — I had written; θα έχω γράψει — I will have written. Past perfect is also called pluperfect.
Mood
A grammatical category used for different kinds of expression. The tables distinguish indicative, subjunctive and imperative.
Indicative
Forms used in ordinary statements and questions: γράφεις — you write / are you writing? Intonation and context help distinguish the question.
Subjunctive
Forms commonly introduced by να, for example θέλω να φύγω — I want to leave. Continuous and simple forms express different aspects: να γράφω versus να γράψω. “Simple” here does not mean past.
Imperative
A form used to give an instruction or make a request: γράψε το όνομά σου — write your name; γράψτε — write, addressed to several people or politely to one.
Active and middle/passive
Sets of verb forms: γράφω — I write; γράφεται — it is written. Form alone does not determine meaning: έρχομαι means I come, despite its middle/passive ending.
Deponent
A verb used in middle/passive forms without a corresponding everyday active set with the same meaning. θυμάμαι — I remember — is an example. Do not invent an active counterpart just because the ending looks passive.
Impersonal
A verb used without a personal subject in its impersonal construction, normally in third-person forms: πρέπει να φύγω — I must leave, literally “it is necessary that I leave”. The verb after να changes with the person: πρέπει να φύγουμε — we must leave.
Participle
A verb-related form that can describe an accompanying action or a state. γράφοντας means while writing; γραμμένος, γραμμένη, γραμμένο mean written and change to agree with what they describe. Context determines the construction.
Irregular verb
A verb with forms that cannot all be predicted from a common pattern: βλέπω — I see; είδα — I saw. Learn the useful forms together.
Register: everyday, formal or literary
The style or setting in which a form is used. A form labelled formal or literary may be valid but unsuitable for ordinary conversation. Follow the entry’s usage notes.
