Hold on to wine from Tokyo as a souvenir (8)
I believe the answer is:
keepsake
'souvenir' is the definition.
(synonyms)
'hold on to wine' is the wordplay.
'hold on to' becomes 'keep' (synonyms).
'wine' becomes 'sake'.
'keep'+'sake'='KEEPSAKE'
'from tokyo as a' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for keepsake that I've seen before include "Remembrance" , "Gift, reminder" , "to remember one by" , "Thing retained in memory of giver" , "one recalls" .)
