  1. with no concern about the consequences of one's action; carelessly.

Etymology

Origin of recklessly

reckless ( def. ) + -ly

Explanation

Acting recklessly means doing something without stopping to think about the consequences of your action. If you recklessly throw a football near your neighbor's house, you may end up paying to repair a broken window. The adverb recklessly is nearly the same as carelessly, with one difference: doing something recklessly implies that your action is potentially dangerous in some way. Driving recklessly is always a terrible idea, as is recklessly spending every last dollar in your bank account. This risky word can be traced back to the Old English receleas, "careless, thoughtless, or heedless."
