In ordinary terms, a teasing poser (5)
I believe the answer is:
prose
'in ordinary terms' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'a teasing poser' is the wordplay.
'poser' can be anagrammed to 'PROSE'.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for prose that I've seen before include "Text" , "Literary genre" , "Writings not in verse" , "Gossipy talker" , "Non-verse" .)
