A purpose clause names the goal an action is intended to achieve. Greek normally uses για να, can use plain να after verbs of motion, and uses ώστε να / έτσι ώστε να in more careful formulations. Greek has no productive, free infinitive to fill the English to + verb purpose slot, so the purpose verb is conjugated. A restricted invariant verb form survives inside perfect constructions such as έχω γράψει, but it cannot stand alone as an English-style purpose infinitive.
για να: the everyday standard
Για να is the neutral default for an intentional goal: “in order to” or purpose “so that.” In this prototypical use, για names the purpose relation and να introduces an envisaged event rather than an asserted fact.
Ήρθα για να συζητήσουμε το πρόγραμμα της επόμενης εβδομάδας.
írtha ya na sizitísume to próghrama tis epómenis evdhomádhas
I came so that we could discuss next week's schedule.
Κρατάω σημειώσεις για να θυμάμαι τι συμφωνήσαμε.
kratáo simiósis ya na thimáme ti simfonísame
I take notes so that I remember what we agreed.
Έκλεισα την πόρτα για να μην ακούγεται ο θόρυβος.
éklisa tin pórta ya na min akúyete o thórivos
I closed the door so that the noise wouldn't be heard.
The negative is για να μη(ν) because this is a να-clause. Here μην keeps ν before the vowel of ακούγεται. The detailed alternation belongs to purpose clauses with (για) να.
Plain να after motion and directed action
After common verbs of going, coming, running, stopping, or sending, the movement itself already points toward a goal. Greek therefore often leaves out για and uses plain να. This is neutral and especially frequent in everyday speech.
Πάω να δω αν χρειάζεται κάτι η γιαγιά.
páo na dho an chriázete káti i yayiá
I'm going to see whether Grandma needs anything.
Πετάχτηκα να πάρω ψωμί πριν κλείσει ο φούρνος.
petáchtika na páro psomí prin klísi o fúrnos
I popped out to get bread before the bakery closed.
Both πάω να δω and πάω για να δω are grammatical. The full form makes the purpose more explicit or contrastive; plain να is lighter. After a verb that does not itself imply directed action, για να prevents ambiguity.
Different subjects use the same construction
English distinguishes I came to talk from I spoke loudly so that everyone could hear. Greek uses a conjugated να-clause in both. The verb ending tells you who performs the goal.
Μιλάω δυνατά για να με ακούνε όλοι.
miláo dhinatá ya na me akúne óli
I'm speaking loudly so that everyone can hear me.
Σου στέλνω τον χάρτη για να μη χαθείς.
su stélno ton chárti ya na mi chathís
I'm sending you the map so that you don't get lost.
In the first sentence, ακούνε has a different understood subject from μιλάω. Nothing like English for them to is needed. This is one of Greek's structural advantages: subject reference is carried by the finite ending, not by switching constructions.
ώστε να and έτσι ώστε να
Ώστε να and fuller έτσι ώστε να mean “so as to / in such a way that.” They are common in instructions, administration, and carefully planned prose (formal). They present the outcome as the designed consequence of a method, rule, or arrangement.
Η αίτηση πρέπει να υποβληθεί έγκαιρα, ώστε να εξεταστεί πριν τη συνεδρίαση.
i étisi prépi na ipovlithí éngera, óste na eksetastí prin ti sinedhríasi
The application must be submitted in time so that it can be examined before the meeting. (formal)
Το σύστημα σχεδιάστηκε έτσι ώστε να περιορίζει τα λάθη.
to sístima schedhiástike étsi óste na periorízi ta láthi
The system was designed so as to reduce errors. (formal)
In conversation, για να would be natural in both. The heavier form foregrounds the relationship between the means and the intended outcome.
Aspect inside the goal
The purpose conjunction does not choose aspect for you. The perfective dependent form packages the intended event—or a finite, delimited series—as a bounded whole. The imperfective presents the goal from inside, as a process, maintained state, or open-ended habit. Event count and actual completion do not mechanically decide the choice.
Δούλεψα όλο το απόγευμα για να τελειώσω την αναφορά.
dhúlepsa ólo to apóyevma ya na telióso tin anaforá
I worked all afternoon to finish the report. (bounded intended outcome)
Ανοίγω το παράθυρο κάθε πρωί για να μπαίνει καθαρός αέρας.
anígho to paráthiro káthe proí ya na béni katharós aéras
I open the window every morning so that fresh air can come in. (process presented internally)
English can use the same infinitive shape across these readings, hiding a contrast that Greek expresses in the verb stem. The Greek speaker chooses whether to package the intended situation as bounded or view it internally/open-endedly; a single event may receive the latter view, and a finite repeated series may receive the former.
Purpose versus an actual result
Compare an intention with a consequence that actually occurred:
Χαμήλωσε τη μουσική για να κοιμηθεί το παιδί.
chamílose ti musikí ya na kimithí to pedhí
She turned the music down so that the child could sleep. (purpose)
Χαμήλωσε τόσο πολύ τη μουσική, ώστε το παιδί αποκοιμήθηκε αμέσως.
chamílose tóso polí ti musikí, óste to pedhí apokimíthike amésos
She turned the music down so much that the child fell asleep immediately. (asserted result)
The first sentence reports a goal; it does not guarantee success. The second asserts what followed. The full overlap is mapped on result conjunctions, while clause placement belongs to purpose and result clauses.
Common Mistakes
1. Combining the factual complementizer ότι with purpose να. English “so that” does not contain Greek ότι.
❌ Δουλεύω πολύ ότι να τελειώσω νωρίς.
Incorrect—an intended goal takes για να.
✅ Δουλεύω πολύ για να τελειώσω νωρίς.
dhulévo polí ya na telióso norís
I'm working hard so that I can finish early.
2. Calquing English preposition plus -ing. Greek needs a finite να-clause after για.
❌ Πήγα στο γραφείο για μιλώντας με τη διευθύντρια.
Incorrect—Greek does not use the active participle as the object of για.
✅ Πήγα στο γραφείο για να μιλήσω με τη διευθύντρια.
pígha sto ghrafío ya na milíso me ti dhiefthíndria
I went to the office to speak with the director.
3. Reversing the fixed sequence για να. The two elements cannot exchange places.
❌ Πάω να για πάρω καφέ.
Incorrect—the explicit conjunction is για να; after πάω, plain να is also possible.
✅ Πάω στην κουζίνα για να φτιάξω καφέ για όλους.
páo stin kuzína ya na ftiákso kafé ya ólus
I'm going to the kitchen to make coffee for everyone.
Key Takeaways
- Για να is the everyday default for an intentional goal.
- Motion verbs commonly take plain να: πάω να δω.
- Same-subject and different-subject purpose use the same finite construction.
- Ώστε να / έτσι ώστε να are more formal and foreground a designed outcome.
- Perfective presents a goal as bounded, including a finite series; imperfective presents its internal course, a maintained state, or an open habit.
- A linker alone does not prove purpose: ώστε να, and in degree frames even για να, can introduce a result.
