Reversing a touch to get information (4)
I believe the answer is:
data
'information' is the definition.
(thesaurus)
'reversing a touch' is the wordplay.
'reversing' shows that the letters should be reversed in order.
'touch' becomes 'tad' (I've seen this in other clues**).
'a'+'tad'='atad'
'atad' backwards is 'DATA'.
'to get' acts as a link.
(Other definitions for data that I've seen before include "Listed facts" , "tables, perhaps" , "Facts - Star Trek android" , "Series of measurements" , "Statistical information" .)
