Versatile new pad fits in a bench (9)
I believe the answer is:
adaptable
'versatile' is the definition.
(I've seen this before)
'new pad fits in a bench' is the wordplay.
'new' indicates anagramming the letters.
'fits in' is an insertion indicator.
'bench' becomes 'table' (I've seen this in other clues).
'pad' with letters rearranged gives 'dap'.
'a'+'table'='atable'
'dap' placed inside 'atable' is 'ADAPTABLE'.
(Other definitions for adaptable that I've seen before include "Able to adjust to circumstances" , "Flexible, adjustable" , "Changing with changed conditions" , "Able to adjust to new conditions" , "Good at fitting in to new circumstances" .)
