Start with alcohol and Jack on about bloomers! (6)
I believe the answer is:
errata
'start with alcohol and jack on about bloomers' is the definition.
I can't judge whether this definition defines the answer.
'start with alcohol and jack on about' is the wordplay.
'start with' says to take the initial letters.
'and' says to put letters next to each other (I've seen this in other clues).
'jack' becomes 'tar' (both are informal terms for sailor).
'on' becomes 're' ('on' can be mean 'with reference to').
'about' says the letters should be written backwards.
The initial letter of 'alcohol' is 'a'.
'tar'+'re'='tarre'
'tarre' written backwards gives 'errat'.
'a' after 'errat' is 'ERRATA'.
Can you help me to learn more?
(Other definitions for errata that I've seen before include "Boobs in a book" , "List of mistakes (in book)" , "mistakes in print" , "List of text corrections to be made in a publication" , "Mistakes in printed proofs" .)
