With servant around, one left on depressing journey (10)
I believe the answer is:
pilgrimage
'journey' is the definition.
(I know that pilgrimage is a type of journey)
'with servant around one left on depressing' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'left' could be 'l' (common abbreviation) and 'l' is present in the answer.
'depressing' could be 'grim' (synonyms) and 'grim' is found in the answer.
'servant' could be 'page' (page can mean a boy servant) and 'page' is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pilgrimage that I've seen before include "journey to shrine" , "Religiously-inspired journey" , "Religious traveller's journey" , "Holy journey" , "Religiously inspired journey" .)
