what does diabolical mean

“Diabolical” basically means extremely evil, cruel, or wicked, often in a way that feels devilish or fiendishly planned. In modern English (especially British and informal use), it can also just mean something is very bad, unpleasant, or annoying, like a “diabolical performance” or “diabolical traffic.”

Core meaning: “diabolical”

• The word comes from roots related to “devil” (like Spanish “diablo”), so its original sense is “devil-like” or satanic.

• It’s stronger than words like “bad” or “terrible” and often suggests intentional harm or malice (a “diabolical plan,” a “diabolical plot”).

• Dictionaries define it as “extremely evil,” “fiendish,” or “morally bad and evil; like a devil.”

If someone carefully plans to hurt others or cause chaos, people might call that a “diabolical scheme.”

Softer and informal uses today

Language has loosened the word a bit, especially in everyday or humorous contexts.

You’ll see “diabolical” used for:

• Very bad or awful experiences
  • “The food was diabolical.” (meaning terrible).

• Extremely difficult or tricky things
  • “That puzzle was diabolical.”

* “The final boss is diabolical!” (in games).

• Over-the-top or “so bad it’s kind of funny” moments
  • A nightmare commute, a brutal exam, or a horribly complicated recipe might be called “diabolical” in a dramatic, exaggerated way.

Online and in forums, people also use it more loosely to mean “crazy/over the top,” sometimes even playfully or flirtatiously, depending on tone.

Context does a lot of work: “a diabolical dictator” is deadly serious; “a diabolical homework assignment” is just strong exaggeration.

Quick usage guide

• Serious/strong:
  • “a diabolical crime,” “a diabolical regime,” “a diabolical act of cruelty” → extremely evil, deliberate.

• Negative but not literally evil:
  • “the weather was diabolical,” “that movie was diabolical” → very bad/terrible.

• Dramatic or humorous exaggeration:
  • “this exam is diabolical,” “that level design is diabolical” → fiendishly hard, over the top.

If you’re unsure, remember: the closer the situation is to genuine harm or real malice, the more “diabolical” keeps its original “devilishly evil” punch.

TL;DR:

• Main sense: extremely evil, devilish, intentionally wicked (a “diabolical plan”).

• Everyday sense: very bad, terrible, or fiendishly difficult, often used for dramatic effect.
