'ambiguously' originates from Latin, specifically the word 'ambiguus,' where 'ambi-' meant 'both' and 'agere' meant 'to drive.' 'explained' comes from Latin 'explanare,' where 'ex-' meant 'out' and 'planare' meant 'to make level.'

'ambiguus' transformed into the French word 'ambigu,' and eventually became the modern English word 'ambiguous.' 'explanare' transformed into the French word 'expliquer,' and eventually became the modern English word 'explain.'

Initially, 'ambiguus' meant 'going here and there,' but over time it evolved into its current meaning of 'open to more than one interpretation.' 'Explanare' meant 'to make clear,' which has largely remained the same in modern usage.
