Headless corpse on ship starts to enter yearlong journey (7)
I believe the answer is:
odyssey
'journey' is the definition.
(odyssey is a kind of journey)
'headless corpse on ship starts to enter yearlong' is the wordplay.
'headless' means to remove the first letter.
'corpse' becomes 'body' (I've seen this before).
'on ship' becomes 'ss' (I am not sure about the 'on' bit.**).
'starts to' indicates taking the first letters.
The initial letters of 'enter yearlong' is 'ey'.
'body' with its initial letter removed is 'ody'.
'ody'+'ss'+'ey'='ODYSSEY'
Can you help me to learn more?
(Other definitions for odyssey that I've seen before include "Homer's epic poen about great journey" , "'Long eventful journey, such as that of Ulysses (7)'" , "Book" , "Homer's epic poem" , "Epic wanderings of 13 across" .)
