Case section of canal Egypt added (6)
I believe the answer is:
locket
'case' is the definition.
(I know that locket is a type of case)
'section of canal egypt added' is the wordplay.
'section of canal' becomes 'lock' (canals have locks).
'egypt' becomes 'et' (I've seen this in other clues).
'added' says to put letters next to each other.
'lock'+'et'='LOCKET'
(Other definitions for locket that I've seen before include "Neck adornment" , "Case for carrying memento" , "Small ornamental case hung round the neck" , "'Small piece of jewellery, it opens (6)'" , "Small ornamental case on a necklace" .)
