Husband has green bouquet crossing big road (9)
I believe the answer is:
economise
'husband' is the definition.
(synonyms)
'green bouquet crossing big road' is the wordplay.
'green' becomes 'eco' (abbreviation for ecological).
'bouquet' becomes 'nose' (I've seen this in another clue).
'crossing' is an insertion indicator.
'big road' becomes 'mi' (resembles M1 motorway. I am not sure about the 'big' bit.).
'nose' enclosing 'mi' is 'nomise'.
'eco'+'nomise'='ECONOMISE'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for economise that I've seen before include "Cut back on expenses, be thrifty" , "cut costs" , "Make savings" , "cut services" , "Keep down costs" .)
