irréalisable

Irrealisable is a French adjective that translates to unrealizable, impracticable, or unachievable in English. It describes something that cannot be brought into reality or accomplished, often due to inherent difficulties, limitations, or contradictions. The concept of irrealisable can apply to a wide range of situations, from abstract ideas to concrete plans.

In a practical sense, an irrealisable project might be one that requires resources beyond what is available, relies on technologies that do not yet exist, or faces insurmountable logistical challenges. For instance, a plan to build a city on the moon with current technology would be considered irrealisable. Similarly, a business proposal that promises unrealistic profits with no viable strategy would also fall into this category.

The term can also be used in a more philosophical or theoretical context. An irrealisable idea might be one that is logically inconsistent or fundamentally at odds with the known laws of nature. For example, the idea of a square circle is irrealisable because it contains a logical contradiction. Concepts that defy the basic principles of physics or mathematics are often described as irrealisable.

Identifying something as irrealisable is not necessarily a negative judgment. It can be a crucial step in problem-solving, allowing individuals and groups to recognize the limitations of their goals and redirect their efforts toward more achievable outcomes. It encourages a realistic assessment of possibilities and fosters innovation by highlighting the need for new approaches or technologies to overcome perceived irrealisability.
