# Solute and Solvent classification in a Solution

When I look up the definition of solute and solvent, the definition by the Oxford English Dictionary is

solute

/ˈsɒljuːt,sɒˈljuːt/

noun

the ***minor*** component in a solution, dissolved in the solvent.


What does minor imply here? Does it classify them as solute and solvent as per mass/volume comparison? Or does it refer to their concentration?
