Lois embraces Romeo, the beast! (5)
I believe the answer is:
loris
'beast' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I can't see?
'lois embraces romeo' is the wordplay.
'embraces' indicates putting letters inside.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'lois' placed around 'r' is 'LORIS'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for loris that I've seen before include "Small nocturnal primate" , "Short-tailed mammal" , "Nocturnal primate of Southeast Asia (usually slender or slow)" , "Slow-moving nocturnal primate" , "lemur" .)
