Decussate is a verb that means to intersect or cross.

The Latin word decussare (day coo SAR ay) means ‘to divide crosswise.’ This is the origin of our word of the day. Here’s an example of it:

Finding the hotel isn’t difficult. You simply have to find the place where all the highways decussate, and once you find this X, you simply get on I-95 and you’re there.
