Figures move around on board ship in the east filling chest (5,3)
I believe the answer is:
chess set
'figures move around on board' is the definition.
I know that 'board' relates to this answer.
'ship in the east filling chest' is the wordplay.
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'in' indicates putting letters inside.
'the east' becomes 'e' ('E' can be a synonym of 'east').
'filling' means one lot of letters goes inside another.
'e' going inside 'chest' is 'cheset'.
'ss' inserted into 'cheset' is 'CHESS SET'.
Can you help me to learn more?
(Other definitions for chess set that I've seen before include "It's played with kings, queens and bishops" , "King, pawns etc." , "Game with kings, queens and bishops" , "It's played on a chequered board with 32 pieces" , "men, along with the board" .)
