Ship carries nothing fancy (7)
I believe the answer is:
baroque
'fancy' is the definition.
(similar in meaning)
'ship carries nothing' is the wordplay.
'ship' becomes 'barque' (barque is a type of ship).
'carries' indicates putting letters inside (inserted letters carried inside).
'nothing' becomes 'O' (O resembles 0).
'barque' enclosing 'o' is 'BAROQUE'.
(Other definitions for baroque that I've seen before include "Ornate architectural style" , "Elaborately ornamented" , "Style of e.g. Wren, Bach" , "Bach's music style" , "Florid" .)
