'compostura' originates from Spanish, specifically the word 'compostura', ultimately from Late Latin 'compositura' (from Latin 'componere' meaning 'to put together')

'compostura' developed from Late Latin 'compositura' into Old Spanish forms and eventually into modern Spanish 'compostura', carrying the sense of 'putting together' into meanings of repair and order

Initially it meant 'the act of putting together or composing'; over time it evolved into senses of 'repair/mending' and 'composure/being in order' in modern usage
