Company on board in struggle to make artificial fabric (7)
I believe the answer is:
viscose
'artificial fabric' is the definition.
(viscose is a synthetic fibre)
'company on board in struggle to' is the wordplay.
'company' becomes 'co' (abbreviation).
'on board' indicates putting letters inside (inserted letters are taken on board).
'in' is an insertion indicator.
'struggle' becomes 'vie' (to vie is to struggle or contend with).
'to' becomes 'ss' (I am not sure about this - if you are sure you should believe this answer much more).
'vie' going around 'ss' is 'visse'.
'co' inserted within 'visse' is 'VISCOSE'.
'make' acts as a link.
Can you help me to learn more?
(Another definition for viscose that I've seen is " Type of rayon".)
