What is the greek word for care?

There isn't one single Greek word that perfectly translates to the English "care" because the English word encompasses several different meanings. Depending on the nuance you want to convey, several Greek words could be appropriate:

* Μέριμνα (merimna): This is often the closest translation and implies worry, concern, or anxiety about something. It suggests a burden of care.

* Φροντίδα (frontida): This translates to care, attention, or looking after someone or something. It's a more neutral term than *merimna*.

* Επιμέλεια (epimeleia): This refers to diligent care, attention to detail, and meticulousness.

* Αγάπη (agapē): This means love, but in certain contexts, it can imply deep care and affection.

The best choice depends entirely on the context in which you're using the word "care."
