A word for a “canopy” in The Etymologies of the 1930s, a combination of N. dae “shadow” and N. telu “roof” (Ety/TEL; EtyAC/DAY).

Neo-Sindarin: Since Tolkien seems to have later abandoned the meaning “shadow” for N. dae, I would not use this word for “canopy” in Neo-Sindarin, and would use other words like esgal or [N.] orthelian instead.
