Wedding celebration in one of the ports (4)
I believe the answer is:
ruby
This clue could be a double definition.
'wedding celebration' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'one of the ports' is the second definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'in' is the link.
Can you help me to learn more?
(Other definitions for ruby that I've seen before include "Deep red - transparent gemstone" , "Stony girl" , "Deep 6 across" , "Gemstone - shade of red" , "Vivid red" .)
