Meanings

Adjective

  1. not giving enough attention or thought to avoid mistakes or harm

  2. casually unconcerned or indifferent

Beyond the definition

Imagine a child building a tower of blocks, rushing without carefully stacking each one. That's being careless – acting without enough thought or attention. It doesn't necessarily mean intentionally causing harm, but rather failing to take the necessary precautions. You might be careless with your belongings, leaving them scattered around, or careless with your words, saying something you regret. A careless driver isn't trying to crash; they're simply not paying close enough attention to the road. Sometimes carelessness is a minor annoyance, like misplacing your keys or leaving a light on. Other times, it can have serious consequences.
