Gelid is an adjective that means icy or extremely cold.

The Latin word gelu (JAY loo) means ‘frost’ or ‘intense cold.’ The word can be used as a literal reference to something icy or very cold as in ‘The pond was gelid that evening,’ or it can be used metaphorically as in: I was hoping for a warm reception at the reunion, but when I got a gelid greeting from everyone, I had a feeling their memories of me weren’t very fond.
