An unreal conditional asks the listener to enter a world different from the actual one. Greek marks that distance with past forms after αν and with θα + a past form in the result. The imperfect readily imagines a different present and can also receive past reference from context; the pluperfect explicitly reconstructs a bounded finished past.
The central pairings
| Meaning | Condition | Result |
|---|---|---|
| unreal present or general hypothesis | αν + imperfect | θα + imperfect |
| missed past event | αν + pluperfect | θα + pluperfect |
| past state leading to a missed event | αν + imperfect | θα + pluperfect |
| past event with a present consequence | αν + pluperfect | θα + imperfect |
The first two rows are the clean teaching patterns. The other two are not exceptions or errors: they let each clause locate its own time. This is why Greek counterfactuals cannot be reduced to one mechanical tense-matching rule.
A different present: imperfect in both clauses
Use αν + imperfect → θα + imperfect when the imagined condition conflicts with the present or describes a remote general possibility.
Αν είχα δικό μου γραφείο, θα δούλευα πιο ήσυχα.
an ícha dhikó mu ghrafío, tha dhúleva pio ísicha
If I had my own office, I would work more quietly.
Αν ήσουν εδώ, θα ξέραμε τι να κάνουμε.
an ísun edhó, tha ksérame ti na kánume
If you were here, we would know what to do.
The imperfects είχα, δούλευα, ήσουν, and ξέραμε are past in form but present in reference. They tell us that the condition is remote from reality: I do not have an office; you are not here. English similarly uses past forms in if I had or if you were, but Greek also inflects the equivalent of “would” for person and number.
Αν μέναμε στη Θεσσαλονίκη, θα πηγαίναμε συχνότερα στη θάλασσα.
an méname sti Thesaloníki, tha piyéname sichnótera sti thálasa
If we lived in Thessaloniki, we would go to the sea more often.
A different finished past: pluperfect in both clauses
For two completed events that did not happen, the canonical explicit pairing is αν + pluperfect → θα + pluperfect. The pluperfect is είχα + invariant perfect form; in this neutral pattern θα appears only in the result.
Αν μου είχες στείλει τη διεύθυνση, θα είχα έρθει νωρίτερα.
an mu íches stíli ti dhiéfthinsi, tha ícha érthi norítera
If you had sent me the address, I would have come earlier.
Αν είχαμε κλείσει τραπέζι, δεν θα είχαμε περιμένει τόση ώρα.
an íchame klísi trapézi, dhen tha íchame periméni tósi óra
If we had booked a table, we wouldn't have waited so long.
Both sentences look backward at a closed opportunity. They can convey regret, criticism, or a neutral explanation. The grammar does not itself decide the speaker's attitude; tone and context do.
States and events need not use the same form
Some past conditions are states, not completed events. Greek naturally uses the imperfect for states such as knowing, being able, or being somewhere, even when their consequence belongs to the finished past.
Αν το ήξερα, θα σου το είχα πει από χθες.
an to íksera, tha su to ícha pi apó chthes
If I had known, I would have told you yesterday.
Αν μπορούσα τότε, θα είχα έρθει να σε βοηθήσω.
an borúsa tóte, tha ícha érthi na se voithíso
If I had been able to then, I would have come to help you.
Here ήξερα and μπορούσα describe unreal past states; θα είχα πει and θα είχα έρθει describe missed completed actions. This mixed pairing is the regular semantic choice, not a defective version of the all-pluperfect pattern.
Conversely, a missed past event can produce a present consequence:
Αν είχα δεχτεί εκείνη τη δουλειά, τώρα θα έμενα στην Πάτρα.
an ícha dhechtí ekíni ti dhuliá, tóra tha émena stin Pátra
If I had accepted that job, I would be living in Patras now.
That time contrast is developed on mixed conditional types.
Imperfect counterfactuals with past reference
Θα + imperfect can describe an unreal past result when context already makes the past time clear. This is a neutral, established use rather than merely an informal shortcut; the condition may also remain imperfect.
Αν ήξερα ότι θα κρατούσε τόσο, δεν θα ερχόμουν.
an íksera óti tha kratúse tóso, dhen tha erchómun
If I'd known it would take so long, I wouldn't have come.
Time is recovered from the completed act of coming and from context. Δεν θα είχα έρθει makes the missed completion explicit and is useful whenever the context would otherwise permit a present or future reading; the imperfect version is not “bad Greek” or inherently casual.
English “would” versus Greek θα
English would and would have are useful anchors, but θα is not itself a conditional tense. The verb following it supplies tense, aspect, person, and number: θα ταξίδευα “I would travel,” θα ταξιδεύαμε “we would travel,” θα είχαμε ταξιδέψει “we would have travelled.” The verb forms themselves are covered on present conditional forms and perfect conditional forms.
Common Mistakes
1. Using a future result for an explicitly missed past consequence.
❌ Αν οι γονείς μου έμεναν κοντά, θα μας βοηθήσει χθες.
Incorrect—the future θα μας βοηθήσει cannot locate the unreal result at χθες.
✅ Αν οι γονείς μου έμεναν κοντά, θα μας είχαν βοηθήσει χθες.
an i ghonís mu émenan kondá, tha mas íchan voithísi chthes
If my parents lived nearby, they would have helped us yesterday.
2. Dropping predicate agreement inside the imagined condition.
❌ Αν αυτή η δουλειά ήταν πιο εύκολος, θα έμενα στην εταιρεία.
Incorrect—εύκολος is masculine, but the feminine subject η δουλειά requires εύκολη.
✅ Αν αυτή η δουλειά ήταν πιο εύκολη, θα έμενα στην εταιρεία.
an aftí i dhuliá ítan pio éfkoli, tha émena stin etería
If this job were easier, I would stay at the company.
3. Treating “would” as invariant and losing Greek agreement.
❌ Αν είχαμε περισσότερο χώρο, θα αγόραζα εμείς μεγαλύτερο τραπέζι.
Incorrect—the overt subject εμείς requires the first-person plural αγοράζαμε.
✅ Αν είχαμε περισσότερο χώρο, θα αγοράζαμε εμείς μεγαλύτερο τραπέζι.
an íchame perisótero chóro, tha aghorázame emís meghalítero trapézi
If we had more room, we ourselves would buy a bigger table.
Key Takeaways
- Present unreal: αν + imperfect → θα + imperfect.
- Missed completed events: canonically αν + pluperfect → θα + pluperfect.
- Past states may stay imperfect, and a past condition can have a present imperfect result.
- Θα + imperfect may neutrally refer to a missed past result when context supplies the time; the pluperfect makes completion explicit.
