adjective
able to use both hands with equal skill
The word 'ambidextrous' comes from the Latin roots 'ambi-' meaning 'both' and 'dexter' meaning 'right'. While it originally referred to the ability to use both hands equally well, it is now commonly used to describe someone who is generally versatile or skillful.
