Two companies get no backing for manufacture of silky case (6)
I believe the answer is:
cocoon
'silky case' is the definition.
(I've seen this in another clue)
'two companies get no backing' is the wordplay.
'two companies' can mean two replacements for 'company'.
'company' becomes 'co' (abbreviation).
'company' becomes 'co' (abbreviation).
'get' says to put letters next to each other.
'backing' shows that the letters should be reversed in order.
'no' written backwards gives 'on'.
'co'+'co'+'on'='COCOON'
'for manufacture of' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cocoon that I've seen before include "Silky case protecting a pupa" , "Protective covering around some animal eggs" , "Envelop for protection" , "Silky sheath around a chrysalis" , "protective clothing" .)
