Goes straight over, embracing it with juvenile ebullience (7)
I believe the answer is:
beeline
'goes straight' is the definition.
'beeline' can be an answer for 'straight' (thesaurus). I am not sure about the 'goes' bit.
'embracing it with juvenile ebullience' is the wordplay.
'BEELINE' is hidden back-to-front within the letters.
However, I am unsure how this is indicated.
'over' acts as a link.
Can you help me to learn more?
(Other definitions for beeline that I've seen before include "Undeviating route" , "To make a -- for is to go without deviation" , "Shortest route between A and B" , "Direct track" , "Most direct route" .)
