Centre to be rebuilt in modern style (6)
I believe the answer is:
recent
'rebuilt in modern style' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs occasionally mean the same thing.
'centre to be' is the wordplay.
'to be' indicates anagramming the letters.
'centre' with letters rearranged gives 'RECENT'.
Can you help me to learn more?
(Other definitions for recent that I've seen before include "Not long ago, a little while back" , "Not long ago, just a little while past" , "In the near past, not long ago" , "Done not long ago" , "Just gone by" .)
