'incrementally-changed' originates from the word 'incremental,' which comes from the Latin 'incrementum,' meaning 'growth' or 'increase,' combined with 'changed,' from the Old English 'ceosan,' meaning 'to choose.'

'incremental' evolved from the Latin 'incrementum' through Middle English, while 'changed' evolved from the Old English 'ceosan' to the modern English 'change.'

Initially, 'incremental' meant 'growth or increase,' and 'changed' meant 'to choose or decide.' Over time, 'incrementally-changed' came to mean 'altered in small steps.'
