Meaning and background
The story behind Duo
Duo entered English in a musical sense for two voices before broadening to a pair of people. Its route passes through Italian or French to the Latin word for two. That gives an owner a partnership or music association, even when Duo is the name of just one dog. The apparent mismatch can be intentional rather than a problem to correct. If you want the name to reflect a particular companion relationship, explain that personal story alongside the straightforward pair-related vocabulary.
- Origin
