'contraction-centered' originates from the combination of 'contraction' and 'centered', where 'contraction' comes from Latin 'contractio', meaning 'a drawing together'.

'Contraction' evolved from the Latin 'contractio' through Old French 'contraction', and 'centered' from the Latin 'centrum'.

Initially, 'contraction' referred to the act of drawing together, but in modern usage, it also refers to shortened forms of words.
