In plain words
When a word reaches a second meaning without ever letting go of its literal one, that function is called ajahatī, the non-abandoning. It works in "the red one runs"; here, it is not the one to take.
Close to the Sanskrit
That word-function whose application is upon another meaning while not abandoning the literal meaning — this is called ajahatī, 'the non-abandoning'; as in 'the red one runs', it is not to be accepted here.
