“Practice makes a man perfect”, so goes the saying. So what makes a woman perfect? Perhaps she already is. Alright, that was lame. But that’s not the point of this post.
Consider the sentence: “No practice makes a man perfect”. Does it mean that not doing any practice makes a man perfect (and practice ruins perfection), or that, no amount of practice will make a man perfect? Is there any grammatical mistake in this sentence or does it convey two contrasting but legitimate meanings? Does this phenomenon has a linguistic definition? What are other examples of such kind?
