Understanding current things differently (7)
I believe the answer is:
Here is my best explanation:
'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'.
(Other definitions for insight that I've seen before include "ability to perceive clearly", "Practical knowledge", "what psychoanalysts hope to gain", "vision", "perspicacity", "comprehension", "Intuitive understanding", "Things I have understanding of", "Acute understanding" and "famous Sunday Times team".)
