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 subsidiary indication.
'current' becomes 'i' (symbol for electric current).
'differently' indicates an anagram.
'things' with letters rearranged gives 'nsight'.
(Other definitions for insight that I've seen before include "Awareness", "Deep understanding", "Deep perception of a situation", "Perceptiveness", "The ability to perceive the true nature of something", "Special knowledge", "Perception", "Understanding", "Things I have understanding of" and "Intuitive understanding".)
