Get lost regularly going round that French city (5)
I believe the answer is:
lyons
'french city' is the definition.
(I've seen this before)
'get lost regularly going round' is the wordplay.
'get' becomes 'yon' (I can't justify this - if you can you should give a lot more credence to this answer).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'going round' means one lot of letters goes inside another (some letters go around others).
The alternating letters of 'lost' are 'ls'.
'yon' placed within 'ls' is 'LYONS'.
'that' is the link.
Can you help me to learn more?
(Other definitions for lyons that I've seen before include "City of central France" , "Capital of Rhone department of France" , "anglicised French place name" , "old-world tea shops" , "French city" .)
