Ship almost loaded with silver bags (7)
I believe the answer is:
luggage
'bags' is the definition.
(I've seen this before)
'ship almost loaded with silver' is the wordplay.
'ship almost' becomes 'lugge' (I can't justify this - if you can you should believe this answer much more).
'loaded with' means one lot of letters goes inside another.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'lugge' enclosing 'ag' is 'LUGGAGE'.
Can you help me to learn more?
(Other definitions for luggage that I've seen before include "Bags of the traveller" , "(Traveller's) suitcases" , "Suitcases and travelling bags" , "Suitcases for journey" , "case?" .)
