Allotted place in rubber thongs (5)
I believe the answer is:
berth
'allotted place' is the definition.
'berth' can be an answer for 'place' (synonyms). I'm unsure of the 'allotted' bit.
'in rubber thongs' is the wordplay.
'in' indicates the answer is hidden within the clue.
'BERTH' can be found hidden inside 'rubber thongs'.
Can you help me to learn more?
(Other definitions for berth that I've seen before include "Ship's bunk" , "Bunk on board" , "Place to lie down on train or ship" , "Bunk on ship or train" , "Accommodation on a ship" .)
