I was a bit lost trying to figure out what to do with Cee’s Challenge this week: 4-Letter Words Starting with ‘D’; then I decided to Google the phrase and lo and behold, a list of almost 300 words appeared. Even then I had trouble finding a suitable word until almost the end I saw the word ‘dune’!
Aha! a collection of dunes around the world.
