Definition - Purl (noun)

I wanted to explore the definition of the word purl because knit has so many meanings. Let's look at purl as a noun.

Definition of PURL

• gold or silver thread or wire for embroidering or edging
• the intertwisting of thread that knots a stitch usually along an edge
• purl stitch
  

I think it is interesting that knit (as the kind that is relevant to this blog) is giving a real descriptive definition for the craft, where as purl only describes the stitch with the word. Not a very illuminating definition!
