Lie with gusto outrageously? One might (8)
I believe the answer is:
eulogist
'one might' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'lie with gusto outrageously?' is the wordplay.
'with' means one lot of letters go next to another.
'outrageously?' is an anagram indicator (I've seen 'outrageously' mean this).
'lie' after 'gusto' is 'gustolie'.
'gustolie' is an anagram of 'EULOGIST'.
Can you help me to learn more?
(Other definitions for eulogist that I've seen before include "One who extols another" , "One praising another" , "One who sings the praises of another" , "One giving high praise" , "good speaker" .)
