What's discussed in work penned by jerk (5)
I believe the answer is:
topic
'what's discussed' is the definition.
I can't judge whether this defines the answer.
'work penned by jerk' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'penned by' means one lot of letters goes inside another.
'jerk' becomes 'tic' (jerking movement by the body).
'op' placed inside 'tic' is 'TOPIC'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for topic that I've seen before include "Something to discuss" , "Content of argument" , "Subject (of a talk, etc)" , "Subject (of speech, etc)" , "Subject (of, eg, speech)" .)
