Blow Up in a Sentence: Meaning and Examples

Blow up at a glance

• Blow up is a phrasal verb with four common senses: explode, inflate, enlarge and lose your temper.
• The explode, rage and intensify senses are intransitive, so no object follows.
• The inflate and enlarge senses are transitive and separable: blow up the photo or blow the photo up.

What does blow up mean?

Blow up is a phrasal verb meaning to explode, to fill with air, to make something larger, or to become suddenly angry. The Cambridge entry for blow up records the explosion and the inflation senses, and context decides which one a reader hears. To explode is the single-word verb for the first sense, while to inflate covers the second and to enlarge covers the third.

The limitation is worth stating plainly. Blow up is informal and physical, so it is the wrong verb for a calm, controlled increase; grow or escalate serve better when nothing bursts or loses control.

How do you use blow up in a sentence?

The explode, rage and intensify senses are intransitive, so nothing follows the verb. The inflate and enlarge senses are transitive and separable, and a pronoun object must sit inside the verb.

The split is not optional with a pronoun: blow up it is impossible, so blow it up is the only grammatical form, and that one rule reveals which senses are separable and which are not.

Blow up in a sentence: examples across contexts

Blow up jumps between a kitchen, a news desk and a football pitch, and the sense changes with the scene. The nine sentences below keep the verb while moving the meaning.

Only the anger and explosion sentences leave nothing after the verb, which is the quickest way to tell the intransitive senses from the transitive ones. To erupt is the nearest single-word verb for the sudden-anger sense.

Blow up vs blow out

Blow up and blow out share a verb but point in different directions. Blow up bursts outward or grows; blow out bursts a tyre, extinguishes a flame, or ends with a sudden loss, and the two are swapped constantly by learners.

Verdict: choose blow up for growth, explosion or temper, and blow out when something is snuffed, burst or widening, so the blow out pair is best told apart by what happens to the air. To implode is its inward opposite, because that verb collapses rather than bursts.
