'slowly-made' originates from the combination of 'slowly' and 'made', where 'slowly' is derived from 'slow' meaning 'not fast', and 'made' is the past participle of 'make', meaning 'to create'.

'slowly' evolved from Old English 'slāw', and 'made' from Old English 'macian', eventually forming the modern English term 'slowly-made'.

Initially, 'slowly' meant 'not quick', and 'made' meant 'created', which together have retained their meaning in 'slowly-made'.
