8) If you stick to the rules above, you will be correct in almost all cases. However, there are a few exceptions, and the following are the most useful ones to learn: We don’t use a/an before the names of meals: We had lunch at noon. We don’t use a/an before words like school, prison, or college when we are talking about them in a general way:
I hope to go to college.
He spent three years in prison.
With the word ‘hospital’, there is a difference between British and American English:
My brother’s in hospital (UK) / in the hospital (US).
We use the before the names of shops or places where we go for services when they are the ones we usually go to:
I need to go to the supermarket.
She went to the doctor’s.
