The story
- Italian · borrowed fromquel che sarà, sarà“what will be, will be”
- English todayque sera sera
An ungrammatical hispanicization of the artificial Italian language phrase "che sara sara", from standard Italian quel che sarà, sarà (“what will be, will be”), coined by American composers Jay Livingston and Ray Evans for use as the title to their 1956 song “Que Sera, Sera” (as such, this phrase represents an artifice based upon an artifice).
