Some slides aren’t about to get destroyed (6)
I believe the answer is:
erased
'destroyed' is the definition.
(I've seen this before)
'some slides aren't about' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'about' is a reversal indicator.
'desare' is hidden within 'slides arent'.
'desare' in reverse letter order is 'ERASED'.
'to get' is the link.
(Other definitions for erased that I've seen before include "'Wiped out, deleted (6)'" , "torn off" , "Obliterated" , "destroyed the lot" , "removed recording" .)
