In this way Frenchman captures all crashing in an Alpine race? (6)
I believe the answer is:
slalom
'an alpine race?' is the definition.
(I've seen this in another clue)
'in this way frenchman captures all crashing' is the wordplay.
'in this way' becomes 'so'.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'captures' is an insertion indicator.
'crashing' is an anagram indicator.
'so'+'m'='som'
'all' is an anagram of 'lal'.
'som' enclosing 'lal' is 'SLALOM'.
'in' acts as a link.
(Other definitions for slalom that I've seen before include "Downhill ski race over a winding course" , "Type of ski race" , "Winter Olympic event" , "Downhill ski event" , "Winding ski-run" .)
