How to use it
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.
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.
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.
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.
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 Collocations
Common Mistakes
'Pop up' is intransitive — it never takes a direct object. Nothing comes between 'pop' and 'up', and nothing follows 'up' as an object.
'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.
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.
