illogical
B1Pronunciation
UK
- /ɪlˈɒdʒɪkəl/
US
- /ˌɪˈlɑdʒɪkəl/
Description
- not sensible
- unreasonable
- not based on clear thinking
If something doesn't make sense, if the pieces don't fit together in a reasonable way, it's illogical. Imagine trying to build a house with no foundation; that would be an illogical approach. It means it is not based on clear reasoning or common sense.
Sometimes things seem illogical at first glance but have hidden reasons. But something is truly illogical when the conclusion does not follow from the facts. A detective might dismiss a suspect's alibi as illogical if it contains contradictions. Or you might call someone's fear of bananas illogical, unless they had a bad experience involving one.
Illogical describes something that lacks logical reasoning or is inconsistent with established principles of logic. It means deviating from what is reasonable, sensible, or expected based on evidence and sound thinking.
The opposite of logical isn't necessarily wrong; it simply means the connection between ideas isn't clear or valid. An illogical argument might be emotionally appealing but lack factual support. For example, claiming that wearing a lucky hat will guarantee that you win a game is an illogical belief; there is no rational link between the two.
The term can apply to many things: statements ("His explanation was completely illogical"), actions ("It would be illogical to invest all your money in one risky venture"), or even thought processes ("Her reasoning seemed illogical and based on unfounded assumptions").
In formal contexts, like philosophy or debate, "illogical" often refers to specific fallacies, or errors in reasoning. But in everyday conversation, it simply means something doesn't add up or seems unreasonable. It's a word we use when things just don't click into place the way they should.
So, if you find yourself scratching your head and thinking, "That doesn't make any sense!", you've likely encountered something illogical.
