Council worker, say, finding waste outside old chemical company (8)
I believe the answer is:
official
'council worker say' is the definition.
I can't tell whether this definition defines the answer.
'waste outside old chemical company' is the wordplay.
'waste' becomes 'offal' (I've seen this before).
'outside' means one lot of letters goes inside another (some letters go outside others).
'old chemical company' becomes 'ICI' (former company Imperial Chemical Industries).
'offal' placed around 'ici' is 'OFFICIAL'.
'finding' is the link.
Can you help me to learn more?
(Other definitions for official that I've seen before include "agent" , "Sanctioned by authority" , "Authorised - formal" , "Issued by a public authority" , "Public employee" .)
