Sixteen terms. Four groups of four. Find the connection.

How to play

Sort the sixteen terms into four groups of four. Select four tiles, then check the group.

Each group sits at a tier from 1 to 4. Tier 1 is the gentlest, Tier 4 the meanest. You find out which tier you hit only once the group is right.

Get three of the four and you'll be told you're one off. You won't be told which one.

Four wrong guesses ends the grid and reveals the answers.

Several terms are placed to look like they belong somewhere else. That's the puzzle, not a bug.

Nobody is fluent in all of it

Most people in this business are fluent in roughly a quarter of it. You can run accounts for a decade, read the trade press every morning, and still go quiet the moment somebody from another discipline starts using their own words at normal speed. Nobody says so out loud, because in a meeting, nodding is cheaper than asking. So the gaps persist, and they persist in exactly the places where two teams have to agree on something expensive. The useful exercise is not learning more vocabulary. It is finding out, honestly and in private, which words you actually know and which ones you have only ever heard.
