Greek builds new vocabulary by combining stems, not only by adding endings. Once learners recognize pieces such as κακο-, ξανα-, σιγο-, and -μάλλης, an unfamiliar long word often becomes a manageable hypothesis rather than an opaque block. The hypothesis still needs checking: compounds regularly develop meanings that go beyond the sum of their visible parts.
Fused nouns such as ανεμόμυλος, νυχτοπούλι, and οδοντόβουρτσα are treated on compound nouns, including their gender, inflection, spelling, and stress. This page concentrates on verbs and adjectives.
Compound verbs: manner, repetition, excess, and alternation
A first element can modify how the verbal action unfolds. Κακομαθαίνω combines evaluative κακο- with μαθαίνω: depending on its construction, it means to spoil someone or to become accustomed to unduly easy treatment. The meaning is conventional, not simply “learn badly.”
Μην τον κακομαθαίνεις με δώρα κάθε φορά που έρχεται.
min ton kakomathénis me dhóra káthe forá pu érchete
Don't spoil him with gifts every time he comes.
Κακομάθαμε στην ησυχία και τώρα μας ενοχλεί κάθε θόρυβος.
kakomáthame stin isichía ke tóra mas enochlí káthe thórivos
We got too used to the peace and quiet, and now every noise bothers us.
Ξανα- adds “again,” while παρα- in παρακάνω adds excess. These elements attach directly; they do not take the linking -ο-.
Ξαναγράφω την εισαγωγή γιατί η πρώτη εκδοχή ήταν ασαφής.
ksanaghráfo tin isaghoyí yatí i próti ekdhochí ítan asafís
I'm rewriting the introduction because the first version was unclear. (open/internal viewpoint)
Αύριο θα ξαναγράψω την τελευταία παράγραφο από την αρχή.
ávrio tha ksanaghrápso tin teleftéa parághrafo apó tin archí
Tomorrow I'll rewrite the final paragraph from scratch. (bounded viewpoint)
Βάλε λίγο πιπέρι, αλλά μην το παρακάνεις όπως χθες.
vále lígho pipéri, alá min to parakánis ópos chthes
Add a little pepper, but don't overdo it like yesterday.
The contrast ξαναγράφω / ξαναγράψω is ordinary aspect: the first views rewriting from within or as open, the second as bounded. The prefix does not force a “once” or “repeated” interpretation.
Verb + verb and adverb-like first elements
Greek can coordinate two actions inside one verb. Ανοιγοκλείνω describes opening and closing, often repeatedly; αναβοσβήνω describes alternating between being lit/on and unlit/off. A linking -ο- appears between the verbal stems.
Το παιδί ανοιγοκλείνει την πόρτα και ξυπνάει το μωρό.
to pedhí anighoklíni tin pórta ke ksipnái to moró
The child keeps opening and closing the door and waking the baby.
Το λαμπάκι αναβοσβήνει από το πρωί· μάλλον θέλει έλεγχο.
to labáki anavosvíni apó to proí; málon théli élencho
The little light has been blinking since morning; it probably needs checking.
An adverbial first element can contribute manner. Σιγοτραγουδώ means to sing quietly or under one’s breath. The compound is more lexical and compact than an arbitrary adverb–verb phrase.
Σιγοτραγουδούσε καθώς μάζευε τα ποτήρια από το τραπέζι.
sighotraghudhúse kathós mázeve ta potíria apó to trapézi
She was singing softly as she cleared the glasses from the table.
Descriptive adjective compounds
Compound adjectives often package a salient feature into one word. Κοκκινομάλλης describes someone with red hair; καλόκαρδος someone kind-hearted; μεγαλόσωμος someone large-bodied. The compound inflects as an adjective for the person or thing described.
Η κοκκινομάλλα ηθοποιός κάθεται δίπλα στον σκηνοθέτη.
i kokinomála ithopiós káthete dhípla ston skinothéti
The red-haired actress is sitting beside the director.
Ο παππούς της ήταν καλόκαρδος και βοηθούσε όλο το χωριό.
o papús tis ítan kalókardhos ke voithúse ólo to chorió
Her grandfather was kind-hearted and helped the whole village.
Χρειάζεται μεγαλύτερο κλουβί, γιατί είναι μεγαλόσωμο πουλί.
chriázete meghalítero kluví, yatí íne meghalósomo pulí
It needs a larger cage because it is a large-bodied bird.
Some adjective compounds coordinate equal properties: κιτρινόμαυρος is yellow-and-black, while γλυκόξινος combines sweet and sour. Others describe possession: καλόκαρδος is not a kind heart but someone who has one.
Η σάλτσα είναι γλυκόξινη και ταιριάζει πολύ με το ρύζι.
i sáltsa íne ghlikóksini ke teriázi polí me to rízi
The sauce is sweet-and-sour and goes very well with the rice.
Φορούσε ένα κιτρινόμαυρο κασκόλ της ομάδας.
forúse éna kitrinómavro kaskól tis omádhas
He was wearing a yellow-and-black team scarf.
Prefix-like first elements
The boundary between a compound member and a prefix is not always sharp. Productive elements such as ψιλο- “slightly / somewhat” (informal), μισο- “half-, incompletely,” καλο- “well,” and κακο- “badly” resemble words in meaning but behave like bound first elements.
Έξω ψιλοβρέχει, αλλά δεν χρειάζεται μεγάλη ομπρέλα.
ékso psilovréchi, alá dhen chriázete megháli ombréla
It's drizzling outside, but you don't need a big umbrella. (informal)
Άφησε το σχέδιο μισοτελειωμένο πάνω στο γραφείο.
áfise to schédhio misotelioméno páno sto ghrafío
She left the plan half-finished on the desk.
Ο καινούριος υπάλληλος είναι καλοπροαίρετος, αλλά ακόμη άπειρος.
o kenúrios ipálilos íne kaloproéretos, alá akómi ápiros
The new employee is well-intentioned but still inexperienced.
Other families are more clearly analysed as prefixes and are surveyed on prefixes. The useful learner skill is not policing a perfect boundary; it is recognizing recurring left-hand material.
A decoding routine
When you meet an unfamiliar compound:
- Start from the right and look for a familiar verb or adjective base.
- Test whether the preceding -ο- is a linking vowel; the linking-vowel page covers vowel-initial second elements and segmentation traps.
- Give the first element a broad contribution: repetition, manner, evaluation, colour, degree.
- Treat the result as a hypothesis. Context and a dictionary decide whether the word has lexicalized.
Δεν ήξερα τη λέξη «σιγοβράζω», αλλά από τα μέρη της μάντεψα τη σημασία.
dhen íksera ti léksi sighovrázo, alá apó ta méri tis mándepsa ti simasía
I didn't know the word ‘σιγοβράζω,’ but I guessed its meaning from its parts.
Here σιγο- gives a good clue that σιγοβράζω means “cook at a gentle simmer,” yet the exact culinary use remains lexical.
Common Mistakes
Treating every compound as though it were a noun
Noun gender, head position, final-element inflection, and noun-compound stress do not explain how a compound verb conjugates or a compound adjective agrees. First identify the output word class; consult the noun owner page only for nouns.
✅ Η λάμπα αναβοσβήνει όταν πέφτει η τάση.
i lába anavosvíni ótan péfti i tási
The lamp flickers when the voltage drops.
Inserting -ο- after every first element
Prefix-like ξανα- and παρα- attach without the compound linker.
✅ Μην ξανακάνεις την ίδια πληρωμή· έχει ήδη περάσει.
min ksanakánis tin ídhia pliromí; échi ídhi perási
Don't make the same payment again; it has already gone through.
Assuming complete semantic transparency
Use the parts to guess, then confirm the established meaning.
✅ Τον έχουν κακομάθει όλοι και δυσκολεύεται να ακούσει όχι.
ton échun kakomáthi óli ke dhiskolévete na akúsi óchi
Everyone has spoiled him, and he finds it hard to hear no.
Guessing stress from the parts
A compound is a new lexical word. Learn its written accent and pronunciation with it; noun stress in particular is covered by the noun owner page.
✅ Η φίλη μου είναι ξανθομάλλα, όχι κοκκινομάλλα.
i fíli mu íne ksanthomála, óchi kokinomála
My friend is blonde-haired, not red-haired.
Key Takeaways
- Compound verbs can encode repetition, excess, manner, or alternating actions: ξαναγράφω, παρακάνω, σιγοτραγουδώ, ανοιγοκλείνω.
- Compound adjectives package colour, evaluation, or a possessed feature: γλυκόξινος, καλόκαρδος, κοκκινομάλλης.
- ψιλο-, μισο-, καλο-, κακο- behave as productive prefix-like first elements, but derived meanings may lexicalize.
- Decode from the right, identify recurring first material, and verify the resulting hypothesis rather than trusting a literal sum.
