Platform which made bluebird cross? (7)
I believe the answer is:
This might be a double definition.
'platform' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'made bluebird cross?' is the second definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'which' is the link.
Can you help me to learn more?
(Other definitions for twitter that I've seen before include "Chirpy social medium" , "Electronic social network" , "Talk excitedly" , "Sound made by bird" , "Bird's sound; trivial talk" .)
