The Huns, oddly, hiding bronze in locker? (7)
I believe the answer is:
tetanus
'locker?' is the definition.
(I've seen this before)
'the huns oddly hiding bronze' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'hiding' means one lot of letters goes inside another.
'bronze' becomes 'tan' (both can mean to get a sun tan).
'the'+'huns'='thehuns'
The alternating letters of 'thehuns' are 'teus'.
'teus' enclosing 'tan' is 'TETANUS'.
'in' is the link.
(Other definitions for tetanus that I've seen before include "Bacterial disease" , "Disease known as lockjaw from rabid dog bite" , "Attunes (anag) - muscular illness" , "Locker" , "Attunes to disease from dog-bite" .)
