A sailor turns up to deliver lots of charts (5)
I believe the answer is:
atlas
'lots of charts' is the definition.
'atlas' can be an answer for 'charts' (I've seen this before). I am not sure about the 'lots of' bit.
'a sailor turns up' is the wordplay.
'sailor' becomes 'salt' (salt is a kind of sailor).
'turns up' is a reversal indicator.
'salt' backwards is 'tlas'.
'a'+'tlas'='ATLAS'
'to deliver' is the link.
Can you help me to learn more?
(Other definitions for atlas that I've seen before include "Titan compelled by Zeus to support the sky" , "book of world records?" , "Titan who held up the sky" , "travel book" , "Geographical book" .)
