REMAINER anglicism derived from REMAIN verb to remain ( se ) and sust . balance , rest , residue . It became popular in 2016 in England when the plebiscite on Brexit was held to decide whether to leave or stay in the EC. Those who advocated remaining were called REMAINERS, "the left ones." It is easy to adaotate to the colloquial language because in English the term REMINDER is common, which comes from REMIND remember, and means reminder, which is why 3M invented yellow stickers to stick REMINDERS on the refrigerator door, on the landline or in the workplace, used today universally and in various colors.
