Greek Tenses Explained: How Past, Present, and Future Work in Modern Greek

Most guides to Greek tenses do the same unhelpful thing: they hand you a table of eight tenses on day one and leave you to drown in it. You don’t need eight tenses to talk about your day. You need three: the present, the simple past, and the future. Together they cover the large majority of what comes up in real conversation. This article builds those three around a single verb so you can see how one form turns into the next.

Take γράφω (gráfo) — I write. We’ll follow it across now, the past, and the future, and pick up a second verb along the way.

The Present: What’s Happening Now (and What Usually Happens)

The present tense is the form you learn first and the one you’ll lean on most. It covers two things English splits apart:

• Γράφω ένα γράμμα. — I am writing a letter. (happening right now)
• Γράφω κάθε μέρα. — I write every day. (a habit)

Greek doesn’t have a separate “I am writing” construction the way English does. Γράφω does both jobs. So when you want to say what you’re doing right now or what you do regularly, the present handles it:

• Πίνω καφέ κάθε πρωί. — I drink coffee every morning.

This is good news for a beginner. One set of endings, two meanings, and you can already describe routines and what’s going on around you. The full set of present-tense endings, and how verbs split into groups, is covered in Unit 3 of the course.

The Simple Past (Aorist): What You Did

When you want to talk about a finished action in the past (what you did, what happened), Greek uses the aorist, the simple past. This is the past tense you’ll reach for constantly, because it’s how you answer “what did you do?“.

Watch what happens to γράφω:

• Present: Γράφω ένα γράμμα. — I am writing a letter.
• Aorist: Έγραψα ένα γράμμα. — I wrote a letter.

Three things change: the stem shifts (γράφ- becomes γραψ-), the ending changes to the past-tense set, and an έ- appears at the front as a common past-tense marker. Not every verb follows that pattern so neatly. πάω (páo, I go) is irregular so the stem changes entirely:

• Present: Πάω σινεμά. — I go / I am going to the cinema.
• Aorist: Πήγα σινεμά. — I went to the cinema.

The aorist forms can look quite different from the present, which is why they’re worth learning as their own thing rather than trying to derive them under pressure. The reward is large: with the present and the aorist alone, you can talk about now and about what already happened.

The Future: θα and One Small Trick

The future is the easiest of the three, because Greek builds it with one little word: θα (tha). Put θα in front of the verb and you’re talking about the future.

• Θα γράψω ένα γράμμα. — I will write a letter.
• Θα σε δω τη Δευτέρα. — I will see you on Monday.
• Θα πάω σινεμά. — I will go to the cinema.

θα is the future signpost. When you hear it at the start of a verb phrase, the speaker is talking about what’s going to happen. θα itself never changes, so the only new piece each time is the verb form that follows it.

Aspect: The Idea Hiding Behind the Tenses

There’s one concept worth meeting early, even lightly, because it explains why Greek has more verb forms than English: aspect. Greek marks two things about an action: when it happens and how you view it, as either a single completed event or as something ongoing and repeated.

That’s the real difference between Έγραψα ένα γράμμα (I wrote a letter: one finished event) and the continuous past Έγραφα (I was writing, I used to write: ongoing). At A1 you don’t need to master this. Just know that when you meet a second past tense later, it isn’t a different time; it’s a different view of the same time. The three tenses here are your foundation, and aspect is a refinement you add on top.

How to Make Tenses Stick

The trick that works is to learn each new verb in three forms at once: present, aorist, future. For γράφω, that’s γράφω – έγραψα – θα γράψω. For πάω, it’s πάω – πήγα – θα πάω. Say all three together when you meet a verb, the same way you’d learn a noun with its article.

Where this gets tested is in conversation, when someone asks what you did at the weekend and you have to produce the aorist on the spot, not recognise it on a page. That gap between recognising a form and saying it correctly is exactly what speaking practice closes. Speak Greek’s AI feedback tells you when you’ve used the wrong tense, so you can fix it and try again. That’s what moves the three tenses from theory into something you can actually use.

FAQ

How many tenses does Greek have, and do I need all of them? Greek has several tenses, but three do most of the work in everyday speech: the present, the aorist (simple past), and the future with θα. Learn these first and you can talk about now, the past, and what’s coming. The others are refinements you add later.

What is the aorist in Greek? The aorist is the simple past — it describes a finished action, like Έγραψα ένα γράμμα (I wrote a letter) or Πήγα σινεμά (I went to the cinema). It’s the past tense you’ll use most often, especially when answering “what did you do?“.

How do you form the future tense in Greek? Put θα in front of the verb: Θα γράψω (I will write), Θα πάω (I will go), Θα σε δω (I will see you). θα itself never changes, so the only new piece is the verb form that follows it.

Does the Greek present tense mean “I do” or “I am doing”? Both. Γράφω can mean “I write” (a habit) or “I am writing” (right now). Greek doesn’t split these into two forms the way English does, so the present tense covers routines and actions in progress alike.

Why are there two past tenses in Greek? Because of aspect — whether you view a past action as a single completed event (the aorist, Έγραψα) or as ongoing and repeated (the continuous past, Έγραφα). It’s the same point in time, seen two different ways. At A1 the aorist is the one to focus on.
