Poor lines of communication? (8)
I believe the answer is:
doggerel
This might be a double definition.
'poor lines' is the first definition.
'doggerel' can be an answer for 'lines' (lines of poor quality poetry). I am not certain of the 'poor' bit.
'communication?' is the second definition.
(I know that doggerel is a type of rhyme)
'of' is the link.
Can you help me to learn more?
(Other definitions for doggerel that I've seen before include "questionable verse" , "Irregular comic verse" , "Very bad poetry or verse" , "William McGonagall's kind of poetry?" , "Poor poetry" .)
