The word bonusses is a plural form of the noun bonus. The etymology of bonus can be traced back to the Latin word bonus, which means good or favorable. In Latin, it was primarily used as an adjective, but it eventually developed into a noun meaning good thing or something extra. The plural form boni was used in Latin, but as the word entered the English language, it acquired the regular English plural -es ending, resulting in bonuses.
