Cleansing diet - I quit beef! (5)
I believe the answer is:
detox
'cleansing' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'diet i quit beef' is the wordplay.
'quit' indicates named letters should be taken away.
'beef' becomes 'ox'.
'diet' with 'i' removed is 'det'.
'det'+'ox'='DETOX'
Can you help me to learn more?
(Other definitions for detox that I've seen before include "Purge" , "Remove poisons from the body" , "Rid of poison" , "What thalassotherapy may bring" , "possible treatment of alcoholic" .)
