The historic French word "hui" is now completely obsoleted, and commonly found only in the single expression "aujourd'hui", considered now as a single word (so in that case the break will not occur, and you will typically not find the word "hui" in a modern French dictionnary).
"Hui" < "hodie" 'today'. Cf. Spanish "hoy". -- Michael Everson * * Everson Typography * * http://www.evertype.com
