narrow down

reduce a list of options to fewer, more specific ones

B2

What does "narrow sth down" mean?

To narrow down means to take a large set of options, candidates, or possibilities and reduce it to a smaller, more manageable group. It is typically used when you are making a decision or conducting a search and need to move from many choices towards just a few. For example, a hiring manager might start with two hundred applications and narrow them down to a shortlist of ten. The phrasal verb suggests a gradual, deliberate process rather than a single cut — you are progressively closing in on the best options. It is equally at home in everyday conversation, professional contexts, journalism, and academic writing.

Examples

How to use it

narrow down + object

The most common pattern, used when the object is a noun phrase such as 'the list', 'the options', or 'the candidates'.

We need to narrow down the list before the end of the week.

narrow + object + down

With short noun objects, the separated form is very natural and often preferred.

She narrowed the candidates down to a final group of five.

narrow + pronoun + down

When the object is a pronoun, separation is required — the pronoun must come between the verb and the particle.

There are too many choices — let's try to narrow them down.

narrow down + object + to + number/category

Very frequently, the phrase continues with 'to' plus a number or category to show what the set has been reduced to.

The panel has narrowed down the entries to just three finalists.

be narrowed down + to/by

The passive form is natural and common, especially when the agent is not important or not known.

The search has been narrowed down to two possible locations.

Common Mistakes

Pronoun after the particle

With pronoun objects, the pronoun must go between 'narrow' and 'down', not after 'down'. Placing it after the particle is ungrammatical in English.

✗ We need to narrow down it before tomorrow.
✓ We need to narrow it down before tomorrow.
Confusing 'narrow down' with 'rule out'

'Rule out' means to eliminate one specific option completely, whereas 'narrow down' describes the overall process of reducing a larger set to fewer remaining possibilities. They are not interchangeable.

✗ We've ruled out the candidates to just three.
✓ We've narrowed down the candidates to just three.
Missing 'to' before the remaining number or category

When you say what the set has been reduced to, the preposition 'to' is needed before the number or category. Leaving it out sounds incomplete.

✗ They narrowed down the options two finalists.
✓ They narrowed down the options to two finalists.

Usage

This phrasal verb is neutral and works well in both spoken and written English. It is very commonly followed by 'to' plus a number or category: 'We've narrowed it down to three options.'

Frequently Asked Questions
