A/An and Some (Countable Nouns)
When to use a/an, some, or nothing before countable nouns
Singular Countable Nouns Need a Word Before Them
A countable noun in the singular form cannot stand alone. You must put a/an, the, my, this, or another determiner before it.
- She never wears a hat. (not
wears hat) - Did you see the invoice?
- What a long meeting!
If the noun starts with a vowel sound, use an:
- Do you need an umbrella?
- He gave an honest answer.
Saying What Kind of Thing or Person
Use a/an to classify — to say what category something belongs to or what someone’s job is.
| Singular | Plural |
|---|---|
| That’s a useful tool. | Those are useful tools. (no some) |
| She’s an accountant. | They’re accountants. |
| What a great idea! | What great ideas! |
Notice that in the plural, you just use the bare noun — you do not add some when you are classifying.
Jobs
When you state somebody’s job, always use a/an before the singular job title.
- Martin is a project manager. (not
Martin is project manager) - Would you like to be an engineer?
Physical Descriptions
Use a/an before singular features and no article before plural ones.
- She has a friendly face. (not
the friendly face) - He has blue eyes. (not
the blue eyes)
When to Use Some with Plural Countable Nouns
Some has two uses with plural countable nouns.
1. Some = a number of / a few
Use some to mean “a certain number of” or “a few.”
- I’ve attended some good training sessions recently.
- *Some colleagues of mine are transferring to the London office.*
- I need some new headphones.
In many cases, some is optional and the sentence works fine without it:
- I need (some) new business cards.
- The office was empty apart from a desk and (some) chairs.
2. Some = some but not all
Use some to contrast a part of a group with the whole group.
- *Some employees prefer working from home.* (but not all employees)
- *Some branches will close early on Friday, but most will stay open.*
Do Not Use Some for General Statements
When you talk about things in general, use the bare plural — no some.
- I enjoy team meetings. (not
some team meetings) - She writes reports. (not
some reports— this is what she does in general)
