Bright and bouncy? Not yours truly in the morning! (6)
I believe the answer is:
agleam
'bright' is the definition.
(similar in meaning)
'bouncy? not yours truly in the morning' is the wordplay.
I cannot really understand how this works, but
'morning' could be 'am' (as in 12:00 AM) and 'am' is located in the answer.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for agleam that I've seen before include "Shining brightly" , "Bright" , "scintillating" , "Sparkling" .)
