'inaccurately-guided' originates from modern English, specifically from the adverb 'inaccurately' and the past participle 'guided', where the prefix 'in-' meant 'not' and 'accurate' meant 'exact/careful'.

'accurate' changed from Latin 'accuratus' (through Old French and Middle English) and became the modern English 'accurate'; 'guide' changed from Old French 'guider' (with Germanic roots) and became 'guide' in Middle English; these components combined in modern English to form the compound 'inaccurately-guided'.

Initially the components meant 'not exact' (in- + accurate) and 'to lead' (guide); over time the compound came to mean 'led or directed in an inaccurate way'.
