* "Leg" is an English word that comes from the Proto-Germanic word *leggą*, which itself likely comes from a Proto-Indo-European root word *leg-*.
The meaning of "leg" has evolved over time, but it has always referred to a limb of the body.
It's important to remember that not all words have a clear root meaning. Some words are simply borrowed or created, without being directly traceable back to a single root word.
