Understanding current things differently (7)
I believe the answer is:
insight
'understanding' is the definition.
(insight is a kind of understanding)
'current things differently' is the wordplay.
'current' becomes 'i' (symbol for electric current).
'differently' is an anagram indicator.
'things' with letters rearranged gives 'nsight'.
'i'+'nsight'='INSIGHT'
(Other definitions for insight that I've seen before include "famous Sunday Times team" , "Deep understanding" , "Furniture from Princes Street for" , "Perspicacity" , "Perceptiveness" .)
