fancy-free

the compound 'fancy-free' originates from late 16th-century english, first appearing in william shakespeare's play "a midsummer night's dream." the term literally meant "free from the power of fancy (or fantasy)," implying a state of being unswayed by whimsical imagination or desire. over time, the specific association of 'fancy' with amorous inclination led to the dominant modern sense of being unattached romantically and thus carefree. the logic of the word perfectly captures the transition from a general freedom from mental caprice to the more specific and common contemporary meaning of freedom from romantic entanglement.

Structure: fancy (imagination, caprice) + free (without) fancy (middle english, from old french 'fantasie', meaning imagination, caprice; functional role: nominal element describing a mental state) + free (old english 'frēo', meaning not in bondage, exempt from; functional role: adjectival element denoting absence or liberation).
