In short, round about ten end (7)
I believe the answer is:
current
'in short' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'round about ten end' is the wordplay.
'round' is an insertion indicator.
'about' indicates an anagram.
'end' becomes 'curr' (I can't explain this - if you can you should believe this answer much more).
'ten' anagrammed gives 'ent'.
'ent' enclosing 'curr' is 'CURRENT'.
Can you help me to learn more?
(Other definitions for current that I've seen before include "Stream - in the news" , "Flow of air or water" , "Flow, of a river say" , "Happening now" , "Electrical flow" .)
