With help, Solent sorted out a similar place in Turkey (10)
I believe the answer is:
hellespont
'in turkey' is the definition.
('Hellespont' is part of 'turkey')
'with help solent sorted out' is the wordplay.
'with' says to put letters next to each other.
'sorted out' is an anagram indicator.
'help' put next to 'solent' is 'helpsolent'.
'helpsolent' is an anagram of 'HELLESPONT'.
'a similar place' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for hellespont that I've seen before include "Narrow strait" , "separating lovers" , "stretch of water" .)
