What is it called when you have a word down the page and make phrases off of it?

There isn't a single specific term for this activity, but it's a type of word game or puzzle that can be described in various ways:

* Vertical Word Puzzle: This is a general term that describes any puzzle where words are arranged vertically.

* Downward Word Chain: This highlights the sequential nature of creating phrases from the vertical word.

* Word Ladder: This term is often used for puzzles where you transform one word into another by changing one letter at a time, but it can also be applied to this scenario.
