Solemn poem with glee somehow unknown? (5)
I believe the answer is:
elegy
'solemn poem' is the definition.
'elegy' can be an answer for 'poem' (elegy is a kind of poem). I'm not certain of the 'solemn' bit.
'with glee somehow unknown?' is the wordplay.
'with' says to put letters next to each other.
'somehow' is an anagram indicator.
'unknown?' becomes 'y' (algebra).
'glee' with letters rearranged gives 'eleg'.
'eleg'+'y' is 'ELEGY'.
Can you help me to learn more?
(Other definitions for elegy that I've seen before include "lines of regret" , "Mournful song or poem" , "Lines written by poet" , "Mournful poem, lament" , "Sad work" .)
