Hang on - about to leave Holland in a French carriage? (5-3)
I believe the answer is:
wagon-lit
'french carriage?' is the definition.
'wagon-lit' can be an answer for 'carriage?' (wagon-lit is a kind of carriage). I am not sure about the 'french' bit.
'hang on about to leave holland' is the wordplay.
'hang on' becomes 'wait' (I've seen this in another clue).
'about' is an insertion indicator.
'to leave' becomes 'go' (both can mean to depart).
'holland' becomes 'nl'.
'go'+'nl'='gonl'
'wait' enclosing 'gonl' is 'WAGON-LIT'.
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for wagon-lit that I've seen before include "sleeper" , "Sleeping car on continental trains" , "In-law got injured in sleeping car" , "Continental sleeping-car" .)
