Meaning and background
The story behind Hydro
Hydro has two distinct noun senses in Merriam-Webster. One is a British establishment associated with hydropathic treatment; the other is hydroelectric power. These are more precise than treating the standalone word as a general personal name meaning water. A dog’s Hydro may be inspired by a water-related activity or a technical reference, but that particular intention lies beyond the dictionary’s account of the English word.
- Association
- Hydro can denote a British establishment offering hydropathic treatment or hydroelectric power. Source
