Amongst them all, one lying on its own (6)
I believe the answer is:
lonely
'its own' is the definition.
I can't tell whether this defines the answer.
'amongst them all one lying' is the wordplay.
'amongst' says the answer is hidden in the clue.
'LONELY' is hidden within 'them all one lying'.
'on' is the link.
Can you help me to learn more?
(Other definitions for lonely that I've seen before include "Unfrequented" , "In want of company" , "Missing company" , "Solitary and sad" , "By oneself" .)
