'methodically-decorated' originates from the combination of 'methodically' and 'decorated'. 'Methodically' comes from the Greek word 'methodikos', meaning 'systematic', and 'decorated' comes from the Latin word 'decoratus', meaning 'adorned'.

'methodically' changed from the Greek word 'methodikos' to the English word 'methodical', and 'decorated' evolved from the Latin 'decoratus' to the modern English 'decorate'.

Initially, 'methodically' meant 'systematic', and 'decorated' meant 'adorned'. The combined term 'methodically-decorated' retains these meanings, referring to a systematic approach to decoration.
