fall through

fail to happen as planned (a deal, agreement, or plan)

B2

What does "fall through" mean?

To say that a plan, deal, or arrangement 'falls through' means it fails to happen, even though it was expected or agreed upon. It often suggests the failure came unexpectedly, sometimes after a lot of preparation or negotiation — the plan simply never materialised. The phrase carries a slight sense of disappointment or frustration, reflecting how it feels when something you were counting on doesn't work out. It's a versatile expression that works equally well in casual conversation ('our holiday plans fell through'), professional emails ('the contract fell through'), and news reporting ('the merger fell through after months of talks'). One thing that makes this phrasal verb distinctive is that the subject is always the plan, deal, or arrangement itself — never a person.

Examples

How to use it

plan/deal/arrangement + fall through

The most common structure: an inanimate noun referring to a plan or agreement acts as the subject, and 'fall through' is used without any object.

The property deal fell through because the buyer pulled out at the last minute.

fall through + (time/reason adverbial)

Adverbials like 'at the last minute', 'in the end', or 'unexpectedly' are frequently added to explain when or why the plan failed.

Our plans to open a second branch fell through in the end due to rising costs.

if + subject + fall through, ...

Used in conditional sentences to describe what will happen if a plan or deal fails to go ahead.

If the transfer falls through, the club will need to find another midfielder before the deadline.

it + fall through

A pronoun subject ('it' or 'everything') is used when the plan has already been mentioned and doesn't need to be named again.

We were really excited about the collaboration, but it fell through after the initial meeting.

nearly/almost + fall through

Adverbs like 'nearly' or 'almost' can be placed before 'fall through' to indicate the plan came close to failing but ultimately succeeded.

The sponsorship deal almost fell through when negotiations stalled, but both sides agreed to compromise.

Common Mistakes

Using it with an object

'Fall through' is intransitive, meaning it never takes an object. The plan or deal is always the subject — you cannot put a noun or pronoun between or after the verb and particle.

✗ The problem fell the deal through.
✓ The deal fell through because of the problem.
Confusing it with 'fall apart'

'Fall through' means a plan fails to happen at all — it never gets completed. 'Fall apart' suggests something that was already working starts to break down, and can apply more broadly to relationships or organisations, not just plans.

✗ After months of arguing, their business partnership fell through.
✓ After months of arguing, their business partnership fell apart.
Using a person as the subject

'Fall through' always has an inanimate subject — a plan, deal, arrangement, or similar noun. Using a person as the subject gives the phrase a completely different, unrelated meaning.

✗ She fell through when she cancelled the meeting.
✓ The meeting fell through when she cancelled.

Usage

This phrasal verb is neutral in register and works equally well in conversation, business emails, and news articles. The subject is always the plan, deal, or arrangement — never a person.

Frequently Asked Questions

Can 'fall through' be used in the passive voice?

No — 'fall through' cannot be made passive because it is an intransitive verb with no object. You can't say 'the deal was fallen through'. The plan or deal always acts as the subject: 'The deal fell through.'

Can I say 'the deal is falling through' in the present continuous?

This sounds unnatural in most situations. 'Fall through' typically describes a completed failure, so the simple past ('fell through') or present perfect ('has fallen through') are far more common. The present continuous can occasionally work if you're describing something actively collapsing right now, but this is rare.

Does 'fall through' only refer to business deals?

No — while it's very common in business and property contexts ('the merger fell through', 'the house sale fell through'), it applies to any kind of plan or arrangement. You'll often hear it used for personal plans too, such as a holiday, a wedding, or a social arrangement that fails to happen.

Does 'fall through' imply that someone is to blame?

Not necessarily. It simply means the plan didn't happen, without pointing to a specific cause or person at fault. If you want to specify a reason, you can add context: 'The deal fell through because the two sides couldn't agree on price.'

Is it natural to say 'will fall through' in the future?

It's more natural to use 'fall through' in a conditional clause ('if the deal falls through') than with a straight future 'will' ('the deal will fall through'). The conditional structure is the most common way to talk about the possibility of a plan failing in the future.
