Structure with 'Go Off'

The phrasal verb "go off" is typically intransitive in most of its common meanings, which means it doesn't usually take a direct object immediately after the particle "off". Let's explore its various meanings and how they are structured in sentences. Becoming familiar with these structures is essential for using "go off" correctly.

1. To Explode, Fire, or Activate Suddenly (Bombs, Guns, Alarms, Lights)

This is one of the most frequent uses of "go off". It refers to something activating suddenly, often with a sound or light, or a device beginning to operate.

  • Structure: Subject + go off
  • Example 1: The alarm clock went off at 6 AM, waking everyone in the house.
  • Example 2: Suddenly, all the lights in the building went off due to the power cut.

This meaning implies a sudden, often startling event. Think of the sound and action associated with alarms, bombs, or even a camera flash. When you hear that your alarm went off, you know it made a noise to wake you. If fireworks go off, they explode colorfully. This use of "go off" highlights an abrupt start or activation.

2. For Food or Drink to Spoil or Become Bad

When food or drink is no longer fresh or safe to consume, we can say it has "gone off". This is a very practical application of the phrasal verb.

  • Structure: Subject (food/drink) + go off
  • Example 1: Don't drink that milk; I think it has gone off. It smells sour.
  • Example 2: The fish went off quickly because it wasn't kept in the refrigerator during the warm weather.

This usage of "go off" specifically relates to the deterioration of perishable items. It’s a useful phrase for everyday situations concerning food safety and freshness. If something smells bad, tastes strange, or its appearance has changed negatively, it might have gone off. Recognizing this meaning is important for daily life.

3. For an Event to Happen or Proceed in a Particular Way

"Go off" can also describe how an event, like a meeting, a party, or a presentation, proceeded or was executed. It often comments on the success or smoothness of the event.

  • Structure: Subject (event) + go off + (adverb/prepositional phrase describing manner)
  • Example 1: The presentation went off very well, much better than I had expected.
  • Example 2: Despite the initial technical difficulties, the online conference went off without a hitch in the end.

In this context, "go off" often implies a planned event and its outcome. Adverbs like "well," "smoothly," "badly," or phrases like "without any problems" frequently accompany this usage to describe the nature or success of the event. This meaning is key for discussing the unfolding of plans and activities.

4. To Suddenly Become Angry or Start Shouting (Informal)

This informal usage of "go off" describes a person losing their temper, exploding in anger, or starting an angry outburst, often directed at someone or about something.

  • Structure: Subject (person) + go off (+ at someone / + about something)
  • Example 1: He completely went off at the referee for what he considered an unfair call during the match.
  • Example 2: She went off on a long rant about the terrible customer service she received at the restaurant.

When someone goes off in this sense, they are expressing strong, sudden anger or frustration. It's often unexpected and can be quite dramatic. This is a more colloquial use of the phrasal verb "go off", common in informal spoken English. It's important to understand this meaning to catch the emotional tone in conversations.

5. To Leave a Place (Often Suddenly or for a Specific Purpose)

"Go off" can mean to depart from a location. Sometimes this implies a specific destination, a particular reason for leaving, or even a sudden departure.

  • Structure: Subject + go off (+ to + place / + to do + something / + with + someone)
  • Example 1: She went off to university in another city last September.
  • Example 2: He went off in a huff after their argument, slamming the door behind him.

This meaning is similar to "leave" or "depart". The context often provides clues about the reason for leaving or the destination. It can sometimes imply a sudden or emotionally charged departure, especially if paired with an emotion as in "went off in a huff." Understanding the uses of "go off" in this context helps in tracking movements and departures.

6. To Stop Liking Someone or Something (Informal)

This is another common, often informal, meaning where "go off" indicates a loss of interest, affection, or enthusiasm for someone or something that was previously liked.

  • Structure: Subject + go off + someone/something
  • Example 1: I used to love that particular brand of coffee, but I've gone off it recently; the taste seems different.
  • Example 2: He's really gone off the idea of travelling abroad for his holiday since he heard about the potential quarantine measures.

This implies a change in preference or enthusiasm. If you go off something, you no longer find it as appealing as you once did. It's a useful way to talk about changing tastes, opinions, or feelings. This is a subtle but important meaning of "go off" to grasp for understanding personal preferences in conversation.
