"Have no concept of something" is an idiomatic phrase used to describe a situation where an individual or a group lacks understanding or knowledge about a particular idea, experience, or concept. It implies a complete or significant lack of comprehension or familiarity with the subject matter in question.
When someone has no concept of something, it means they are entirely unfamiliar with it and do not possess any understanding or awareness of its nature, characteristics, or implications. This lack of comprehension can arise from various reasons, such as a lack of exposure, education, or prior experience.
For example, if someone says, "He has no concept of personal finance," it suggests that the individual in question lacks understanding or knowledge about managing money or financial matters. They may be oblivious to budgeting, saving, investing, or any other fundamental concepts related to personal finance.
The phrase "have no concept of something" emphasizes the depth or extent of the person's unfamiliarity, indicating a complete absence or significant deficiency in understanding. It implies that the person is unable to grasp the essence or significance of the subject matter, often leading to misguided actions or decisions due to their lack of knowledge or comprehension.
