Reverse a touch to get information (4)
I believe the answer is:
data
'information' is the definition.
(thesaurus)
'reverse a touch' is the wordplay.
'reverse' says the letters should be written backwards.
'touch' becomes 'tad' (I've seen this in other clues**).
'a'+'tad'='atad'
'atad' back-to-front is 'DATA'.
'to get' is the link.
(Other definitions for data that I've seen before include "Facts given" , "tables, perhaps" , "Contents of some banks?" , "Statistical information" , "Computer info" .)
