Obreptitious
Obreptitous is an adjective that means done falsely or secretly. Coming from the Latin word obrepere (oh brep AIR ay) which means ‘to creep upon,’ our word of the day can be thought of as a synonym for ‘sneaky’ or ‘underhanded.’ Example: I don’t know what happened to the last donut in the break room, but I have my suspicions that it was taken through obreptitious means. It’s the only way to explain how someone could have snatched something I was watching so closely.
