I was never good at geography and I can't believe it got me in the NYT Mini Crossword. I was sure the answer to the clue "lines on a map" had to do with lines on a world map, but it doesn't. It actually has to do with everyday maps.

So, put your geography books back on the shelf and take another look at your phone. The answer is probably in there somewhere. Here are some extra hints to help you figure out the answer to "lines on a map."

"COORD", as in "coordinate", was my guess, but it is not the answer because of the 5D and 6D solutions. Also, the abbreviations "latitude", "longitude" or "time zones" do not work.

This guide is not about a world map, but about maps that you use for navigation, for example in your phone's GPS apps.
