Strain to support article from Berlin, prominent feature at oil-well (7)
I believe the answer is:
derrick
'berlin prominent feature at oil-well' is the definition.
I can't judge whether this definition defines the answer.
'strain to support article' is the wordplay.
'strain' becomes 'rick' (I've seen this before).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'support article' becomes 'der' (I can't justify this - if you can you should give a lot more credence to this answer).
'rick' put after 'der' is 'DERRICK'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for derrick that I've seen before include "boy" , "Frame over an oil well" , "Tower over a borehole" , "Lifting device" , "Oil well framework" .)
