Tunis ruins contain some items not removed from their original location (2,4)
I believe the answer is:
in situ
'not removed from their original location' is the definition.
I can't tell whether this defines the answer.
'tunis ruins contain some items' is the wordplay.
'ruins' indicates anagramming the letters.
'contain' indicates putting letters inside.
'some' suggests taking the first letters.
The initial letter of 'items' is 'i'.
'tunis' is an anagram of 'instu'.
'instu' going around 'i' is 'IN-SITU'.
Can you help me to learn more?
(Other definitions for in situ that I've seen before include "Appropriately positioned" , "In the natural position (Latin)" , "Latin meaning 'on site'" , "Being in the original position, not having been moved" , "Without being moved" .)
