An important part of cultural awareness is understanding that different cultural spheres can use the same word in different ways.

For example, in most European languages, "actual" means "current", and "concurrency" means "competition".

In the crypto space, "DAO" means "project", and "official" means "scam".

My favorite thing to do after moving to the UK is collect examples where words mean the exact opposite. 

Example: “punt” in the U.S. comes from American football and is to delay something2not have to deal with it now. 

In the UK “to take a punt on” is “take a bet on” and is seen in an aggressive  context.
