'ambidextrous' originates from Latin, specifically the word 'ambidexter,' where 'ambi-' meant 'both' and 'dexter' meant 'right-handed.'

'ambidexter' transformed into the English word 'ambidextrous,' and eventually led to the formation of 'ambidextrousness' as a noun.

Initially, it meant 'able to use both hands equally well,' and this meaning has largely remained the same in modern usage.
