noun
A direct loanword from English, used in Japanese to refer to the act of recalling past experiences, often with a nostalgic or literary tone. Less common than native alternatives like 回想 (かいそう).
彼のエッセイは子供時代のレミニセンスに満ちている。
His essay is full of reminiscences of his childhood.
回想 is the standard Japanese word for 'recollection' or 'retrospection', while レミニセンス is a literary loanword often implying a nostalgic, personal reminiscence.
Borrowed from English 'reminiscence'.
