Ships seen by setter, oddly, in a London thoroughfare (5,6)
I believe the answer is:
fleet street
'thoroughfare' is the definition.
(Fleet Street is an example)
'ships seen by setter oddly in a london' is the wordplay.
I cannot quite see how this works, but
'ships' could be 'fleet' (eg a naval fleet) and 'fleet' is located in the answer.
an anagram of 'setter' is 'street' which is within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fleet street that I've seen before include "Collective name for British journalism" , "Part of London which became synonymous with journalism" , "Metaphor for British national newspapers" , "Traditional newspaper area of London" , "Thoroughfare associated with paper industry" .)
