What 𛲐 means
It marks a word part at either end. French Duployan puts it after a root as the suffix «-cion»; Pernin’s English shorthand puts it before a root as the prefix «ex-». A suffix ends a word; a prefix begins one.
Émile Duployé’s shorthand was published in 1860 for quick French writing. Pernin’s English adaptation was in print by 1882. Le Jeune adapted Duployan for Chinook Jargon, a regional contact language, and several Salish languages in British Columbia; that branch uses no affix marks.
