pop up

appear suddenly or without warning

B2

What does "pop up" mean?

To pop up means to appear suddenly and unexpectedly, as if from nowhere. The emphasis is always on the surprise element — something wasn't there before, and now it is, often without warning. It works equally well for physical things (a new shop appearing on a familiar street), digital content (an ad or error message appearing on a screen), and more abstract things (a name repeatedly appearing in conversations, or a memory suddenly coming to mind). The present continuous is especially natural with this verb, particularly when describing ongoing trends: 'New delivery apps keep popping up every month.' It's a neutral, versatile phrasal verb that fits comfortably in both everyday speech and casual writing.

Examples

How to use it

subject + pop up

The core intransitive pattern — no object follows. The subject is whatever appears unexpectedly.

A notification popped up while I was in the middle of my presentation.

subject + keep + popping up

Used with 'keep' to describe something that appears repeatedly, often to the speaker's surprise or mild frustration.

His name keeps popping up in every conversation about the project.

subject + pop up + everywhere / all over + place

Add a location phrase to describe something appearing in many places at once, often describing a trend.

Bubble tea shops are popping up all over the city.

subject + pop up + out of nowhere / from nowhere

These phrases intensify the sense of unexpectedness, emphasising that the appearance was completely unannounced.

An old acquaintance popped up out of nowhere at the conference.

whenever / if + clause + pop up

Used in conditional or temporal clauses to talk about what to do or what happens when something appears unexpectedly.

If any problems pop up during the installation, just restart the app.

Common Mistakes

Using it as a transitive verb

'Pop up' is intransitive — it never takes a direct object. Nothing comes between 'pop' and 'up', and nothing follows 'up' as an object.

She popped up a new browser window.
A new browser window popped up.
Confusing 'pop up' with 'come up'

'Come up' can describe something arising or being mentioned in a more neutral or gradual way, while 'pop up' specifically implies suddenness and the element of surprise. If something was expected or scheduled, 'pop up' is unlikely to fit.

The topic of salary came up out of nowhere in the meeting — I wasn't expecting it to pop up at all on the agenda.
The topic of salary popped up out of nowhere — it wasn't even on the agenda.

Usage

Pop up is neutral and works in both spoken and written English. The related compound noun 'pop-up' (a pop-up shop, a pop-up ad) is also very common and worth learning alongside the verb.

Frequently Asked Questions

Can 'pop up' describe both physical things and digital things?

Yes — that's one of the reasons it's so useful. It works for physical appearances (a new café popping up on your street) and digital ones (an ad or error message popping up on your screen), as well as abstract things like a memory or an idea popping up unexpectedly. The common thread is always the sudden, unplanned nature of the appearance.

Is 'pop-up' (with a hyphen) the same as 'pop up'?

'Pop-up' with a hyphen is a related compound noun or adjective, as in 'a pop-up shop', 'a pop-up ad', or 'a pop-up restaurant'. It's worth learning alongside the verb since both forms are very common. The verb form has no hyphen: 'new shops are popping up everywhere.'

Does 'pop up' always refer to something happening just once?

Not necessarily. It can describe a single sudden appearance ('an error popped up') or something that appears repeatedly ('the same issue keeps popping up'). When used with 'keep' or adverbs like 'constantly' or 'everywhere', it often describes a recurring pattern or an emerging trend.

Can I use 'pop up' to talk about a person appearing somewhere?

Yes, though it has a slightly informal, often metaphorical feel when used for people. It works well when someone appears unexpectedly or seems to turn up in surprising places or contexts — for example, 'He pops up at every industry event' or 'She popped up in my feed again.' For simply saying someone arrived somewhere, 'turn up' is often more natural.

Is there any tense I should avoid with 'pop up'?

Most common tenses work naturally with 'pop up'. The present continuous and simple past are especially frequent. Avoid highly complex tenses like the future perfect continuous — they sound forced and unnatural with this verb. Keep it simple: 'popped up', 'is popping up', or 'keeps popping up' will cover most situations.
