Etymology
The word 'flathead' is a transparent compound formed from two native English elements, 'flat' and 'head', directly describing a physical characteristic. Its primary application is in zoology, naming various fish species whose most distinguishing feature is a dorsoventrally compressed skull. This literal descriptive logic was later extended metaphorically or descriptively to other domains, such as tools (e.g., flathead screw) and, through external observation and naming, to certain Indigenous peoples. The term exemplifies how English readily creates new, concrete vocabulary through the straightforward combination of existing, familiar words.
