Climbing school joined up around top of range - that’s a sight for the morning (7)
I believe the answer is:
dewdrop
'morning' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dewdrop that I've seen before include "A little water" , "Powder'd (anag.)" , "A globule of morning moisture" , "Precipitation" , "Bit of condensed water" .)
