'slowly-structured' originates from the combination of 'slowly' and 'structured', where 'slowly' means 'at a slow pace' and 'structured' means 'organized or arranged'.

'slowly-structured' combines the adverb 'slowly' from Old English 'slāw' meaning 'slow' and the adjective 'structured' from Latin 'structura' meaning 'a fitting together, building'.

Initially, it meant 'organized at a slow pace', and this meaning has largely remained the same in modern usage.
