Showing equality, further education to benefit millions (7)
I believe the answer is:
uniform
'showing equality' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'further education to benefit millions' is the wordplay.
'further education' becomes 'uni' (I am not sure about this - if you are sure you should believe this answer much more).
'to benefit' becomes 'for' (I've seen this in another clue).
'millions' becomes 'm' (abbreviation for millions).
'uni'+'for'+'m'='UNIFORM'
Can you help me to learn more?
(Other definitions for uniform that I've seen before include "Unchanging in form or character" , "Unchanging, showing no variation" , "Military clothes" , "Alike all over" , "Always the same, like army clothes" .)
