Etymology

curious = cur<care> + ious<adjective suffix>

  1. cur (from Latin cura meaning "care, concern")
    • Reflects the idea of attention or interest.
  2. ious (Latin-derived suffix forming adjectives, indicating "full of" or "having the quality of")
    • Conveys a state or characteristic (e.g., "delicious" = full of delight).

Etymology Origin:
The word curious traces back to Latin curiosus ("careful, diligent, inquisitive"), derived from cura ("care"). Over time, the meaning shifted from "careful" to "eager to learn," reflecting a metaphorical extension of "care" as intellectual attention. The suffix -ious solidified its adjectival form, emphasizing a trait of inquisitiveness.
