Like some exercises writer needed after a chocolate bar? (9)
I believe the answer is:
anaerobic
'like some exercises' is the definition.
'anaerobic' can be an answer for 'exercises' (anaerobic exercise is a kind of exercise). I'm not certain of the 'like some' bit.
'writer needed after a chocolate bar?' is the wordplay.
'writer' becomes 'bic' (kind of pen).
'needed after' means one lot of letters go next to another.
'a' becomes 'an'.
'chocolate bar?' becomes 'aero' (chocolate bar. I am not sure about the 'chocolate' bit.).
'an'+'aero'='anaero'
'bic' after 'anaero' is 'ANAEROBIC'.
Can you help me to learn more?
(Other definitions for anaerobic that I've seen before include "functional without O2" , "lacking in inspiration?" .)
