Spot the Frippet: trellis.

 How to get some height in the garden without blocking out the sun - or your neighbours' sun, for that matter - or creating a dry patch where nothing will grow?

Stick up a bit of trellis, of course.

It can go on the walls:

The question, though, is this:

Why does a trellis begin with tre-? Basically, what's it got to do with three?

This:

Spot the Frippet: trellis. This word comes from the Old French treliz, which was a kind of fabric with a very open weave. Before that it came from the Latin trilīcius, which means woven with three threads, from tre- plus līcium, which means thread.
