Souvenir, memento (8)
I believe the answer is:
keepsake
I believe this is a double definition.
'souvenir' is the first definition.
(synonyms)
'memento' is the second definition.
(I've seen this before)
(Other definitions for keepsake that I've seen before include "Thing retained in memory of giver" , "It serves to keep a person in mind" , "one recalls" , "Gift, reminder" , "Souvenir, memento" .)
