English manufacturing source needs frame to make material (6)
I believe the answer is:
embody
'make material' is the definition.
'english manufacturing source needs frame' is the wordplay.
'source' says to take the initial letters (source can mean a beginning or origin).
'needs frame' becomes 'body' (I can't explain this - if you can you should give a lot more credence to this answer).
The first letters of 'english manufacturing' is 'em'.
'em'+'body'='EMBODY'
'to' is the link.
Can you help me to learn more?
(Other definitions for embody that I've seen before include "Give a concrete form to" , "Incorporate or express in visible form" , "Stand for" , "Epitomise" , "Incorporate, represent" .)
