Ways to tell them apart:

etymology
  • Inconceivable often implies something is so unlikely or bizarre that it stretches the limits of belief.
  • Unthinkable indicates that something is not even considered as a possibility due to it being bizarre, horrible, or forbidden.
  • In many contexts, inconceivable tends to emphasize the inability to mentally grasp an idea, while unthinkable leans more towards moral or logical restrictions.
  • If something is inconceivable, it might just be hard to imagine due to logic or complexity, but if it's unthinkable, it might be culturally or ethically unacceptable.
  • Use inconceivable when highlighting the improbability that something could even happen, and unthinkable to stress its unimaginable nature due to extreme consequences.
