You can say this only in the English your mommy taught you:
An hot summer. An high road. An Hell.

Your mommy probably taught you this:
A hour. A honorable lord.

Your mommy was right, as long as the conversation was limited to the four walls of your house, but nowhere else in New Zealand, nor in Britain, nor in the United States of America the above can be deemed grammatically correct.

I was seriously thinking you knew a little bit of English, but now I am convinced that by calling you stupid, I would just be insulting the whole community of people with a low intelligence. Get a life loser.
