formal

Not resulting from or achieved through deliberate planning; unintentional.

Usually describes a mistake or an oversight rather than a lucky accident.

The story behind the word. From the Latin 'in-' (not) and 'advertere' (to turn the mind toward). It literally means 'not turning your mind toward something,' hence an oversight.

Word relationships

  • unintentional: Inadvertent often implies a lack of attention or 'not looking' (advertent).
  • deliberate: Done on purpose after careful thought.

Commonly confused with

  • accidental: Accidental is broader; inadvertent specifically implies a lack of focus or attention.

  • inadvertence (noun): the quality of being inadvertent

Memory hook

In- (not) + Advert (attention). You didn't pay attention to the 'advert' (sign). Not turning your mind toward it.

When not to use

Don't use for positive 'lucky' accidents (use fortuitous).

Fun facts

  • The word 'advert' (as in advertisement) comes from the same root—it's something meant to make you 'turn your mind' toward a product.
