What the pressman produces about dockland area (6)
I believe the answer is:
report
'what the pressman' is the definition.
I can't judge whether this defines the answer.
'about dockland area' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'dockland area' becomes 'port' (ports contain docks).
're'+'port'='REPORT'
'produces' is the link.
Can you help me to learn more?
(Other definitions for report that I've seen before include "Gunfire noise; rumour" , "Statement of fact" , "Complain about - account" , "Announce; gunshot" , "Noise - information" .)
