1. tending or intended to cause delay 2. characterized by procrastination

Sounds a little bit like desultory. Also looks like it should be related to dilate in some way, but I don’t think it is. Before I saw the word in print, I thought dilate was spelled dialate, because that’s the way we pronounced it when I was a kid. It was a little confusing to hear people talking about “dialated” pupils; I expected to see eyeballs spinning, as a dial on a phone would. What a relief to finally get that straightened out.
