To burst in is an English phrasal verb meaning to enter a room, building, or situation suddenly, forcefully, and dramatically, often causing an immediate disruption, surprise, or shock.
How the expression is built depends on whether or not you are naming a specific physical location:
- Burst In (Intransitive — No Direct Object): Used when the room or location is already clear from context or a specific location is not important to name. No noun follows the phrase. Example: “We were having a quiet conversation when the detective suddenly burst in.”
- Burst Into (Transitive — Requires an Object/Place): Used when specifically naming the physical room, building, or space being entered. Example: “Armed police officers burst into the the club.”
- Burst In On (Transitive — Requires an Object/Person): Used when specifically naming the person, group, or meeting being interrupted. Example: “I didn’t mean to burst in on your rehearsal.”
Grammar Note: “Burst In Here” vs. “Burst Into”
Just like with barge in, English learners often wonder why you can say “Don’t burst in here!” without using “into.”
Words like here, there, somewhere, and anywhere function as adverbs of place rather than noun objects. Because they modify the verb directly, “burst in” remains intransitive:
- With Spatial Adverbs: “He came bursting in there shouting for help.”
- With Specific Nouns (Requires “into”): “He came bursting into the conference room shouting for help.”

- “She burst in unannounced and demanded an explanation.” (Burst in + adverb)
- “My kids always burst into my office while I am on video calls.” (Burst into + place)
