I've just come across an interesting article on TreeHugger.com with the title The Future Ain't What it Used to Be. It introduces some drawings from 1900 predicting what life in France is going to be like in the year 2000.
What do you think ain't means in the title of the article?
Now check it in Cambridge Dictionary.
Finally listen to this song and read the lyrics:
Ain't no sunshine when she's gone.
It's not warm when she's away.
Ain't no sunshine when she's gone
And she's always gone too long anytime she goes away.
Wonder this time where she's gone,
Wonder if she's gone to stay
Ain't no sunshine when she's gone
And this house just ain't no home anytime she goes away.
And I know, I know, I know, I know, I know,
I know, I know, I know, I know, I know, I know, I know,
I know, I know, I know, I know, I know, I know,
I know, I know, I know, I know, I know, I know, I know, I know
Hey, I ought to leave the young thing alone,
But ain't no sunshine when she's gone,
Ain't no sunshine when she's gone, only darkness everyday.
Ain't no sunshine when she's gone,
And this house just ain't no home anytime she goes away.
Anytime she goes away.
Anytime she goes away.
Anytime she goes away.
Anytime she goes away.
