Etymology

irresponsible = ir<not> + respons<answer> + ible<capable of>

  • ir<not>: A prefix of negation, derived from Latin in- (not).
  • respons<answer>: From Latin respondere (to answer, promise in return), reflecting accountability.
  • ible<capable of>: A suffix indicating ability, from Latin -ibilis.

Etymology Origin:
The word traces back to Latin responsum (answer), reflecting the idea of being "answerable" for one’s actions. The prefix ir- negates this, creating a term for someone who avoids accountability. Over time, responsible (capable of answering) evolved into its opposite, irresponsible, emphasizing a failure to meet obligations.
