ingenuity

This term describes a specific type of cleverness that manifests as practical problem-solving. It suggests a spark of brilliance used to overcome a limitation or a lack of resources, often evoking an image of a "hack" or a makeshift solution that works surprisingly well. Because it is an abstract quality of the mind, it is treated as an uncountable noun. It does not have a plural form and cannot be counted with numbers; instead, it is measured in degrees, such as having "great ingenuity" or "a touch of ingenuity."
