Selected forms

Look for γράφω → γράφεις: the stress comes before the final -ω. The group helps with present endings; other tenses may use a different stem. Check the tables below.

How to read the verb tables

Start with the present. Find the row for the person you mean: εγώ (I), εσύ (you, singular), αυτός/αυτή/αυτό (he/she/it), εμείς (we), εσείς (you, plural or polite), αυτοί/αυτές/αυτά (they). Greek often leaves out these pronouns because the ending shows the person.

Continuous: over time or repeatedly: έγραφα — I was writing / used to write; θα γράφω — I will be writing. The imperfect is the continuous past.
Simple: an action viewed as a whole: έγραψα — I wrote; θα γράψω — I will write. “Simple” does not mean the action must be short.
Perfect: completed by a reference point: έχω γράψει — I have written; είχα γράψει — I had written; θα έχω γράψει — I will have written.
Subjunctive: forms with να: θέλω να γράφω κάθε μέρα — I want to write every day; θέλω να γράψω ένα μήνυμα — I want to write a message. The sentence supplies the time; the forms distinguish repeated activity from an action viewed as a whole.
Imperative: instructions or requests: γράφε κάθε μέρα — write every day; γράψε το όνομά σου — write your name. These show continuous and simple instructions.
Active and middle/passive: form and meaning: γράφω — I write; γράφεται — it is written. But a middle/passive ending does not always express a passive meaning: έρχομαι means I come.

Alternative forms: commas or slashes separate alternatives. Parentheses mark optional letters, for example γράφουν(ε) means γράφουν or γράφουνε. Alternatives can differ in style or context, so read any usage note before choosing.

A dash or a missing table means a form is not supplied here. Check the entry’s notes; it does not by itself prove that every omitted form is impossible.

Participles and usage · Μετοχές και χρήση

Ξέρω has a present-stem paradigm and the irregular imperfect ήξερα. It has no ordinary simple-past or perfect series; do not construct έχω ξέρει. Έμαθα can express finding out or learning, according to context.
Commands are context dependent; να ξέρεις / να ξέρετε is common for be aware. The adverbial form is ξέροντας.

Δεν ήξερα την απάντηση.

I did not know the answer.
