the word 'tomboy' is a compound formed in the 16th century from the common male name 'tom' and the word 'boy'. initially, it was used as a term for a rude, boisterous male. the application of a male-gendered name ('tom') to a female represents a metaphorical extension, highlighting a perceived deviation from traditional feminine behavior. by the late 16th century, its meaning had shifted specifically to describe a girl who behaves in a manner considered characteristic of a spirited boy, capturing the concept through the literal combination of 'male' + 'child'.
