Dreadful pub documentation (5)
I believe the answer is:
bumph
'documentation' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'dreadful pub' is the wordplay.
'dreadful' becomes 'bum' (bum can mean of bad quality).
'pub' becomes 'ph' (abbreviation).
'bum'+'ph'='BUMPH'
Can you help me to learn more?
(Other definitions for bumph that I've seen before include "Papers" , "Boring documents and written information" .)
