* Παρακαλώ (parakalō): This is the most common and versatile way to express "please." It can be used in most situations.
* Σ' παρακαλώ (s' parakalō): This is a more informal version of "parakalō," used when addressing someone familiarly (like a friend or family member). The "s'" is a contraction of "σε" (se), meaning "you."
* Thank you:
* Ευχαριστώ (efharistō): This is the most common way to say "thank you."
* Ευχαριστώ πολύ (efharistō polý): This means "thank you very much." Adding "πολύ" (polý) emphasizes your gratitude.
So, to summarize: While there's no single word like "please," Παρακαλώ (parakalō) is your go-to. For "thank you," use Ευχαριστώ (efharistō).
