I reach for my mug and set it on the edge of the desk, then turn to grab my phone. I move my attention to the screen and push the mug a bit, not noticing its wobble. A tiny spill begins and I feel my focus slipping, my shoulders tensing. That moment shows how care slips when attention drifts, and I tell myself to adjust, hold the mug steady, and keep my focus on the task.
Real Context
Careless describes a failure to take care or pay attention, often leading to mistakes or accidents. It can refer to actions, habits, or attitudes that show a lack of concern for safety, quality, or consequences. In everyday speech, a careless error is a small slip caused by distraction; a careless person may ignore instructions or not bother checking details. It is stronger than simply inattentive in some contexts, and milder than reckless when speaking about risk. Etymology links to care and the suffix less, meaning without care; the metaphorical image of a child painting carelessly can help learners feel the idea of offhand, sloppy behavior.

- 2. Pair with adjectives like careless mistake, careless handling.
- 3. Contrast with careful to show opposite meaning.
