Ship worker to make treks around the globe (6)
I believe the answer is:
stoker
'ship worker' is the definition.
'stoker' can be an answer for 'worker' (stoker is a kind of worker). I am unsure of the 'ship' bit.
'make treks around the globe' is the wordplay.
'make' indicates an anagram.
'around' indicates putting letters inside.
'the globe' becomes 'o' (O resembles a globe).
'treks' anagrammed gives 'stker'.
'stker' going around 'o' is 'STOKER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for stoker that I've seen before include "Bram ...... created 'Dracula'" , "turning to coke regularly to provide energy?" , "Someone who fuels a furnace" , "piling on the heat?" , "author of scary stories" .)
