The term 'machine-centered' combines 'machine,' from the Latin 'machina,' meaning 'device or contrivance,' and 'centered,' from the Latin 'centrum,' meaning 'center.'

'Machine' evolved from the Latin 'machina' through Old French 'machine' to the modern English 'machine.' 'Centered' evolved from the Latin 'centrum' through Old French 'centre' to the modern English 'centered.'

Initially, 'machine' referred to any device or contrivance, but over time it evolved to refer specifically to mechanical devices. 'Centered' has maintained its meaning of being focused or concentrated around a central point.
