Extremely short poem containing good, hearty fare (6)
I believe the answer is:
stodge
'hearty fare' is the definition.
'stodge' can be an answer for 'fare' (stodge is a kind of food). I am not sure about the 'hearty' bit.
'extremely short poem containing good' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'poem' becomes 'ode' (ode is a kind of poem).
'containing' is an insertion indicator.
'good' becomes 'g' (abbreviation).
'short' with its centre removed is 'st'.
'ode' going around 'g' is 'odge'.
'st'+'odge'='STODGE'
Can you help me to learn more?
(Other definitions for stodge that I've seen before include "Dull work" , "Set dog (anag)" , "Heavy food (colloq.)" , "Heavy solid food" , "Food that's hard to digest" .)
