Willing to move: one is keen, let’s get moving! (11)
I believe the answer is:
telekinesis
'willing' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'to move one is keen let's get moving' is the wordplay.
'to move' indicates anagramming the letters (I've seen 'moving' mean this).
'one' becomes 'i' (Roman numeral).
'get moving' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'i'+'is'+'keen'+'let'='iiskeenlet'
'iiskeenlet' is an anagram of 'telekinesi'.
'telekinesi'+'s'='TELEKINESIS'
Can you help me to learn more?
(Other definitions for telekinesis that I've seen before include "Mental ability to move objects" , "paranormal phenomenon" , "Supposed ability to move objects by thought" , "mind over matter?" , "Ability to move items by mental power" .)
