Havoc as large taxi reversed into river (7)
I believe the answer is:
debacle
'havoc' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'large taxi reversed into river' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'taxi' becomes 'cab' (synonyms).
'reversed' says the letters should be written in reverse.
'into' indicates putting letters inside.
'river' becomes 'dee' (River Dee).
'l'+'cab'='lcab'
'lcab' written backwards gives 'bacl'.
'bacl' going inside 'dee' is 'DEBACLE'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for debacle that I've seen before include "Humiliating failure" , "foul-up" , "A sound defeat" , "Total disorder or defeat" , "Catastrophe" .)
