King had this made afresh to accommodate Republican (5)
I believe the answer is:
dream
'king had this' is the definition.
(Martin Luther King - 'I Have a Dream')
'made afresh to accommodate republican' is the wordplay.
'afresh' indicates anagramming the letters.
'to accommodate' means one lot of letters goes inside another.
'republican' becomes 'r' (abbreviation).
'made' anagrammed gives 'deam'.
'deam' placed around 'r' is 'DREAM'.
(Other definitions for dream that I've seen before include "Sleeper's vision" , "Cherished desire" , "Nocturnal fantasy" , "Fantasise, imagine" , "Illusion" .)
