Disheartened adjutant, observing friction, uses magnetism (10)
I believe the answer is:
attraction
'magnetism' is the definition.
(thesaurus)
'disheartened adjutant observing friction' is the wordplay.
'disheartened' says to hollow out the word (remove centre letters) (the middle or heart is removed).
'observing friction' becomes 'traction' (traction is a kind of friction. I am not sure about the 'observing' bit.).
'adjutant' with its middle taken out is 'at'.
'at'+'traction'='ATTRACTION'
'uses' acts as a link.
Can you help me to learn more?
(Other definitions for attraction that I've seen before include "Something that draws visitors" , "Appeal" , "Pull" , "Popular building/place" , "Interest" .)
