Word Origin

Latin, early 19th century

Why this word?

This adverb is the one-word replacement for the phrase “for argument’s sake.” “Arguendo” is used almost solely in a legal capacity, but it basically means the facts of the matter are to be assumed as true, or are being presented in a hypothetical argument and it doesn’t matter if those facts are true or not. The word “arguendo” might be used to set off a discussion in simplified terms, rather than the more complicated real-life details of a legal case.
