Went in some style to make a score (6)
I believe the answer is:
twenty
'a score' is the definition.
(I've seen this in another clue)
'went in some style to make' is the wordplay.
'in' indicates putting letters inside.
'some' says to take the centre.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'make' becomes 't' (I am not sure about this - if you are sure you should believe this answer much more).
The centre of 'style' is 'y'.
'y' put after 't' is 'ty'.
'went' inserted inside 'ty' is 'TWENTY'.
Can you help me to learn more?
(Other definitions for twenty that I've seen before include "made by Q on a light blue square" , "with two crosses" , "No. between 5 and 1 on dartboard" , "Dozen plus eight" , "Cardinal" .)
