Dont allow one to mix oils with tea (7)
I believe the answer is:
isolate
'dont allow one' is the definition.
I can't judge whether this defines the answer.
'mix oils with tea' is the wordplay.
'mix' indicates anagramming the letters.
'with' means one lot of letters go next to another.
'oils' put after 'tea' is 'teaoils'.
'teaoils' is an anagram of 'ISOLATE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for isolate that I've seen before include "Cut off; quarantine" , "Place apart, away from others" , "Eat soil (anag)" , "Place in seclusion" , "Strand" .)
