Etymology
the term 'hard-wired' originates from mid-20th century electrical engineering and computing. it literally describes electrical components or circuits that are permanently connected by physical wires, in contrast to being programmatically changeable. the metaphorical extension to innate biological or psychological traits leverages the core idea of a fixed, unalterable physical connection. thus, the journey is from describing tangible, manufactured permanence to abstract, inherent characteristics.
Analysis
Structure: hard (firm, fixed) + wire (metal thread) + ed (adjective suffix)
'hard' is from old english 'heard', meaning solid, firm, or severe. 'wire' is from old english 'wīr', meaning metal drawn out into a thread. the suffix '-ed' is from old english '-ed', '-od', '-ad', used to form adjectives from nouns or verbs.
