tomboyish
Tomboyish is an adjective used to describe behaviors, interests, or appearances traditionally associated with boys. A tomboyish girl may enjoy physical activities, outdoor play, informal or practical clothing, and a style that leans away from conventional feminine presentation. The word stems from tomboy, a compound of Tom and boy; earliest attestations date to the early modern period, where it described boisterous boys, and by the 19th century it began to be applied to girls who adopt masculine-leaning behaviors, with tomboyish forming as the corresponding adjective.
In contemporary usage, tomboyish is largely descriptive and nonclinical, indicating a temperament or set of interests
Culturally, tomboyish characters appear in literature, film, and media as portrayals of female autonomy or resistance
