Negation: δεν, μην, όχι

Greek has three words for not, and each has its own job.

• δεν negates normal statements and questions, also before θα: Ο Νίκος δεν μιλάει γαλλικά (Nikos doesn't speak French), Δεν θα έρθω (I won't come).
• μην negates everything after να and makes prohibitions: Μην αγγίξεις! (Don't touch!), Σου είπα να μην αργήσεις (I told you not to be late). Never say να δεν.
• όχι means no and negates a single word that is not a verb: Θέλω τσάι, όχι καφέ (tea, not coffee).

The final -ν stays before a vowel and before κ, π, τ, ξ, ψ, μπ, ντ, γκ, τσ, τζ (δεν έχω, μην πας). Before other consonants it may drop: δε μιλάει, μη φύγεις.
