What is the greek word for commerce?

There isn't one single perfect Greek word for "commerce" that covers all its nuances in English. The best translation depends on the specific aspect of commerce you want to emphasize. However, some possibilities include:

* ἐμπορία (emporia): This is probably the closest single word and refers to trade, commerce, or a marketplace. It's a very common and versatile term.

* χρήμα (chrema): This word means "money" or "wealth," and so could be used in contexts relating to the financial aspect of commerce.

* πράσις (praxis): While not directly translating to "commerce," this word means "action" or "practice," and could be used in the context of commercial *activity*.

The most accurate translation will depend heavily on the context. For most purposes, ἐμπορία (emporia) is the safest and most appropriate choice.
