Hesitate to hit red construction (6)
I believe the answer is:
dither
'hesitate' is the definition.
(thesaurus)
'hit red construction' is the wordplay.
'construction' is an anagram indicator (answer constructed from certain letters).
'hit'+'red'='hitred'
'hitred' is an anagram of 'DITHER'.
'to' acts as a link.
(Other definitions for dither that I've seen before include "Agitate indecisively" , "Be in two minds" , "Waver, vacillate" , "Act in a nervously uncertain manner" , "'Vacillate, hesitate (6)'" .)
