Associate of the Port of London Authority? (3)
I believe the answer is:
pal
This could be a double definition.
'associate' is the first definition.
(a pal is a friend)
'port of london authority?' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'of the' is the link.
Can you help me to learn more?
(Other definitions for pal that I've seen before include "Bud" , "China" , "Brother" , "Mate, informal friend" , "Close friend" .)
