FAQ (8)
Because 'university' starts with a 'y' sound (consonant), not a vowel sound.
Usually no (France, Japan), but yes if the name has 'Republic', 'Kingdom', or is plural (The USA, The UK, The Netherlands).
In a restaurant, yes! It's short for 'a bottle of water' or 'a glass of water'.
It means using no article at all, usually for general plurals or abstract nouns like 'love' or 'cats'.
This is a dialect difference. The UK treats 'hospital' as an institution (like 'school'), while the US treats it as a specific place.
No, we say 'I have breakfast', unless you are talking about a specific breakfast (The breakfast I had yesterday was great).
It is 'an hour' because the 'h' is silent and the word starts with the 'o' sound.
Usually when you talk about the ability to play them: 'I play the flute'.
