Frenchman needing whiskey to get going again (5)
I believe the answer is:
renew
'get going again' is the definition.
(to renew something is to start it again)
'frenchman needing whiskey' is the wordplay.
'frenchman' becomes 'rene' (common French name).
'needing' says to put letters next to each other.
'whiskey' becomes 'W' (alpha bravo charlie delta ...).
'rene'+'w'='RENEW'
'to' acts as a link.
(Other definitions for renew that I've seen before include "Start afresh" , "Replace" , "modernise" , "Revive" , "Renovate" .)
