Both and Both of

BOTH AND BOTH OF
We use both/neither/either for two things. You can use these words with a noun (both books, neither book etc.).
For example, you are talking about going out to eat this evening. There are two restaurants where you can go. You say:
• Both restaurants are very good. (not ‘ the both restaurants’).
• Neither restaurant is expensive.
• We can go to either restaurant. I don’t mind. ( either=one or the other, it doesn’t matter which one)
Both of... / neither of…/ either of…
When we use both/neither/either + of, you always need the …/ these/ those…/ my/ yours/ his/ Tom’s…. (etc.). You cannot say ‘both of restaurants’. You have to say ‘both of the restaurants’, ‘both of those restaurants’ etc. :
• Both of these restaurants are very good.
