Which definition best matches the word abnormal?

• A. Not what is considered to be normal
• B. Not unusual or typical
• C. Different from the usual
• D. Strange

Answer: (D)

Abnormal mainly means deviating from what is normal or expected, often carrying a sense of oddity or peculiarity. The best match here is the idea of something that seems out of the ordinary or unusual to someone observing it. That sense of strangeness captures how we typically experience abnormal—it's not just that it’s not normal, but that it feels noticeably different or unusual.

The other options are less precise for this nuance. Describing something as “not what is considered normal” is technically related but doesn’t emphasize the perception of oddity. “Different from the usual” is close but neutral, whereas abnormal commonly carries a stronger sense of peculiarity. The phrase “not unusual or typical” is awkward and confusing in meaning, and it can muddy the intended sense of deviation.
