Creamy white oil man stirred, containing silver (8)
I believe the answer is:
magnolia
'creamy white' is the definition.
'magnolia' can be an answer for 'white' (I have seen 'Pinkish white' mean 'magnolia' so perhaps 'white' could also mean 'magnolia'). I am unsure of the 'creamy' bit.
'oil man stirred containing silver' is the wordplay.
'stirred' indicates an anagram.
'containing' means one lot of letters goes inside another.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'oil'+'man'='oilman'
'oilman' anagrammed gives 'mnolia'.
'mnolia' placed around 'ag' is 'MAGNOLIA'.
Can you help me to learn more?
(Other definitions for magnolia that I've seen before include "Creamy colour" , "Fragrant bloom and ubiquitous paint colour" , "Omani lag (anag)" , "Tree with creamy-white flowers" , "Fragrant blooms might strangely gain loam" .)
