'expansion-centered' originates from the combination of 'expansion' and 'centered', where 'expansion' comes from Latin 'expansio', meaning 'a spreading out', and 'centered' from Latin 'centrum', meaning 'center'.

'expansion' evolved from the Latin 'expansio' through Old French 'expansion', and 'centered' from Latin 'centrum' through Old French 'centre'.

Initially, 'expansion' meant 'a spreading out', and 'centered' meant 'having a center'. Together, they evolved to mean 'focused on expansion'.
