Transliteration of Russian ги́ря (gírja).
girya (複数形 giryas)
Since the 1940s, the term girya has been mostly replaced by the term kettlebell. Most modern authors treat girya as a transliteration of Russian rather than an English word. However, some authors use girya as an English term in a historical context (referring to its use prior to the 1940s) or when referring to this object in the context of the sport of kettlebell lifting.
