* Επανάλαβε (Epanálave): This is the most common and versatile option. It means "repeat" as a command ("Repeat!") or as a suggestion ("Please repeat"). It's the imperative form of the verb επαναλαμβάνω (epanalambáno - to repeat).
* Επαναλάβετε (Epanalávete): This is the polite form of the above, used when addressing more than one person or someone of higher social standing.
* Ξαναπες (Xanapes): This is a more informal way to say "repeat" (said to one person) meaning something like "Say it again". It's based on the verb λέω (leo - to say).
* Ξαναπείτε (Xanapíte): The polite form of the above.
* Πες το ξανά (Pes to xana): This literally translates to "Say it again" and is also quite informal.
To choose the best word, consider:
* Formality: Are you speaking to a friend or a superior?
* Number of people: Are you addressing one person or multiple people?
* The context of the repetition: Is it a command, a request, or a suggestion?
For most situations, επανάλαβε (epanálave) or επαναλάβετε (epanalávete) will be appropriate.
