The temperature and pressure at which a substance can exist in equilibriumin the liquid, solid, and gaseous states. The triple point of pure water is at
0.01°C (273.16K, 32.01°F)and4.58 mm (611.2Pa)of mercury and is
used to calibrate thermometers.

the triple point is the temperature and pressure at which solid, liquid, and vapor phases of a particular substance coexist in equilibrium. ... The term "triple point" was coined by James Thomson in 1873. Examples: The triple point for water is at 0.01° Celsius at 4.56 mm

"The "triple point of water" is the point where one is interested in all "three phases" of water at a certain "pressure and temperature". The three phases includes ice, water, and vapour. By slightly adjusting either pressure or temperature, one of the "three phases" will change the phase depending on the changes of its environment.
It is called "triple point" because at a particular temperature and pressure for a particular substances, solid, liquid, and vapour phases coexist in equilibrium. It is a specific case of equilibrium of the thermodynamic phase."
