'ambiguously-structured' originates from the combination of 'ambiguous' and 'structured'. 'Ambiguous' comes from Latin 'ambiguus', meaning 'doubtful' or 'uncertain', and 'structured' is derived from Latin 'structura', meaning 'a fitting together, building'.

'Ambiguus' transformed into the Old French 'ambigu', and eventually became the modern English word 'ambiguous'. 'Structura' evolved into the Old French 'structure', leading to the modern English 'structured'.

Initially, 'ambiguous' meant 'doubtful or uncertain', and 'structured' meant 'a fitting together'. Over time, 'ambiguously-structured' came to mean 'having a structure that is not clearly defined'.
