Rule #1: Use A or AN the first time you talk about something that the person listening to you doesn’t know.
- DAVID: “Do you have any pets?”
- JANE “Yes, I have a cat and 2 dogs. The cat is 5 years old and the dogs are 7 and 9.”
In this conversation, Jane says ‘I have A cat’. This is the first time that David has heard this information, and that’s why Jane uses ‘A’. In the next sentence, Jane says ‘THE cat is 5 years old’ because now David knows about her cat.
Rule #2: Use A or AN when it is not important exactly which thing you are talking about.
- Can I borrow a pen? (it doesn’t matter which pen)
- Do you want an apple? (it doesn’t matter which apple)
Rule #3: We use THE when we are talking about a particular item.
- Where is the pen is was using? (the particular pen that speaker had before)
- I ate the apple that was on my desk. (the particular apple that was on the desk)
Here’s an example showing rule #2 and #3:
- DAVID: “Can I borrow a pen?”
- JANE “What happened to the pen that Eric gave you a few minutes ago?”
David asks for any pen, it doesn’t matter which one. Jane replies asking about a particular pen – the pen Eric gave to David.
Rule #4: We only use A or AN for single things (only one).
- He has a car (a single car)
- She has 2 cars (more than one car)
Rule #5: We use THE when there is only one or it is clear which one the speaker is talking about.
- The sun is shining (there is only one sun)
- The Queen of England there is only one Queen of England)
- Your coat is one the chair (it’s clear from what they can see WHICH chair they are talking about)
- I think I left my wallet in the car! (it’s their car or they both know which car they are talking about)
Rule #6: We use AN before a vowel sound and A before a consonant sound.
To understand this rule, you need to know that vowels are the letters A, E, I, O and U and consonants are the other letters (B, C, D etc)
So for example:
- Do you want AN apple or A banana?
Remember that this rule is used on the SOUND of a word, not the spelling. A word like ‘hour’ for example, SOUNDS like ‘our’ because we don’t say the ‘H’, so it take AN, not A. Here are some more examples:
- He works in a university (university SOUNDS like you-niversity, so uses A)
- Berlin is a European country (European sounds like you-ropean, so uses A)
- He’s an FBI agent (FBI sounds like EFF-BI so uses AN)
- He is an honest man (honest sounds like onest, so uses A)
