Disorder of some French chaps taking time crossing mountains (11)
I believe the answer is:
derangement
'disorder' is the definition.
(thesaurus)
'some french chaps taking time crossing mountains' is the wordplay.
'some french' becomes 'de'.
'chaps' becomes 'men' (I've seen this before).
'taking time' becomes 't' (I am not sure about the 'taking' bit.**).
'crossing' is an insertion indicator.
'mountains' becomes 'range' (I've seen this before).
'de'+'men'+'t'='dement'
'dement' enclosing 'range' is 'DERANGEMENT'.
'of' is the link.
Can you help me to learn more?
(Other definitions for derangement that I've seen before include "Disorder; insanity" , "Madness; disorder" .)
