Cast off in a sentence usually means to untie a boat, to throw something away, or to set yourself free from a burden. The phrasal verb is separable, so a sailor casts off the rope or casts the rope off. A simple example is “The crew cast off at dawn.”
Cast off at a glance
- Cast off is a phrasal verb that is usually separable: cast off the rope or cast the rope off.
- Its forms are casts off, cast off and casting off; the past tense never adds -ed.
- The main senses are releasing a boat, discarding something, and freeing yourself from a burden.
- Usual collocations are cast off the lines, cast off old habits and cast off the moorings.

What does cast off mean?
Cast off is a separable phrasal verb with three living senses. The Cambridge entry for cast off records the boating sense and the wider sense of getting rid of something. A sailor casts off the mooring lines; a householder casts off clutter; a person can cast off a habit or a fear. Airlines jettison cargo to save weight, which is a narrower and more technical idea, and everyday speech prefers discard for rubbish.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Release a boat | Untie the lines so a vessel can leave | The ferry cast off from the quay. |
| Discard | Throw away something no longer wanted | We cast off the broken chairs. |
| Free yourself | Let go of a habit, fear or burden | She cast off her old worries. |
| Finish knitting | Work the last row so stitches are secured | Cast off the final row loosely. |
One limitation is worth stating. Cast off sounds odd about people in everyday modern speech: a person can be cast off in a literary or historical sentence, but abandon or reject is the plainer choice. The verb always implies a decisive release, not a routine action.
How do you use cast off in a sentence?
The object may sit between the verb and the particle when it is a noun: cast off the rope or cast the rope off. It must sit between them when it is a pronoun: cast it off, never cast off it. Five patterns cover the realistic uses.
| Pattern | Example | What it signals |
|---|---|---|
| cast off + object | The skipper cast off the lines. | The object follows the particle; neutral word order. |
| cast + object + off | The skipper cast the lines off. | The object moves before off; common with short nouns. |
| cast + pronoun + off | He cast them off before the storm. | A pronoun must sit between verb and particle. |
| cast off (no object) | The ferry cast off at six. | The boating sense allows an intransitive use. |
| cast off + abstract noun | She cast off her doubts. | Figurative release of a feeling or habit. |
Cast off in a sentence: examples across contexts
The verb changes register more than it changes meaning, moving from a knitting pattern to a history essay. Nine sentences show the same phrase at work.
| Context | Example sentence | Why this works |
|---|---|---|
| Sailing | The crew cast off the lines and eased into the channel. | The boating sense with a clear object. |
| Home | We cast off a decade of clutter in one weekend. | Uses the discard sense about possessions. |
| Knitting | Cast off the last row loosely so the edge stays soft. | The technical sense, in an imperative. |
| Conversation | Time to cast off that grudge and move on. | Figurative release of a feeling. |
| News report | The harbourmaster ordered the damaged trawler cast off. | Passive keeps attention on the vessel. |

| Environmental writing | The reef was cast off by the current and drifted away. | The object is a natural thing, not a person. |
| Workplace | The manager cast off three outdated procedures. | A decisive image for removing old rules. |
Only the sailing and news entries keep a boat as the object, and only the knitting entry is a direct instruction. The rest stretch the phrase without breaking it.
Cast off vs cast aside and cast away
Cast off, cast aside and cast away all use the verb cast, but each one releases something different. Setting a plan down without destroying it is cast aside, while total loss or marooning is cast away.
| Attribute | cast off | cast aside | cast away |
|---|---|---|---|
| Core meaning | Release or discard | Set to one side, often temporarily | Throw away completely; maroon |
| Typical object | A rope, habit, clutter | A doubt, a plan, a person | Possessions, a person |
| Reversibility | Usually final | Often provisional | Final and total |
| Register | Neutral to literary | Neutral, slightly formal | Literary or nautical |
| Typical sentence | They cast off the lines. | She cast aside her fears. | The sailor was cast away on a reef. |
To drop something unwanted without ceremony is to shed it. Verdict: choose cast off for a boat leaving or a burden released, cast aside for something set down without destroying it, and cast away for total loss or a marooned person.

For mere rubbish, discard or abandon is plainer.
