Suspect severe cop exposed witness unintentionally (7)
I believe the answer is:
oversee
'suspect severe cop exposed witness unintentionally' is the definition.
I can't tell whether this defines the answer.
'suspect severe cop exposed' is the wordplay.
'suspect' indicates anagramming the letters (a suspicious or unusual spelling).
'exposed' means to look at the middle letters (outside letters removed).
The middle letter of 'cop' is 'o'.
'severe'+'o'='severeo'
'severeo' is an anagram of 'OVERSEE'.
Can you help me to learn more?
(Other definitions for oversee that I've seen before include "Exercise supervision" , "Supervise, keep an eye on" , "Administer" , "Keep an eye on like foreman" , "guide" .)
