headstrong

the compound 'headstrong' is a native english formation from two old english roots. it literally describes a person whose 'head'—their will or intellect—is excessively 'strong' or forceful. this metaphor equates mental stubbornness with physical power, creating an image of an unyielding, self-willed character. the term has been used since the late 16th century to characterize someone who is obstinate and determined to have their own way, prioritizing their own judgment over the counsel or authority of others.

Structure: head (mind, will) + strong (powerful, forceful) head (old english 'hēafod', meaning the upper part of the body, the seat of intellect and will; functional role: noun used attributively to indicate the source of the quality). strong (old english 'strang', meaning powerful, forceful; functional role: adjective describing the nature of the 'head' or will).
