Question 1

What is the difference between Ensure and Insure?

Accepted Answer

Ensure means make sure; insure means take out insurance. In British English that's a clean split. In North American English, insure is also accepted for 'make sure', so 'insure that everyone is safe' is not an error there, but ensure is the choice that works everywhere.
