Business with 1000 quid chemical mixture (8)
I believe the answer is:
compound
'chemical mixture' is the definition.
'compound' can be an answer for 'mixture' (thesaurus). I am not certain of the 'chemical' bit.
'business with 1000 quid' is the wordplay.
'business' becomes 'co' (short for company).
'with' says to put letters next to each other.
'1000' becomes 'M' (Roman numeral).
'quid' becomes 'pound' (synonyms).
'co'+'m'+'pound'='COMPOUND'
Can you help me to learn more?
(Other definitions for compound that I've seen before include "Kind of interest accumulating on capital plus interest" , "Fenced area; chemical substance" , "Living enclosure; type of interest" , "Blended substance - enclosed area" , "Whole formed by two or more elements" .)
