Not prepared to dispatch article with clout (3-3-4)
I believe the answer is:
'not prepared' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes define each other.
'dispatch article with clout' is the wordplay.
'dispatch' becomes 'off' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'article' becomes 'the' (the definite article).
'with' means one lot of letters go next to another.
'clout' becomes 'cuff' (I've seen this before).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for off-the-cuff that I've seen before include "Spontaneous" , "Unofficially - improvised" , "Improvised - extempore" , "Impromptu" .)
