Thwart in a Sentence: Meaning, Examples & Practice

    Cartoon children hold a barrier to stop a rolling ball reaching a tower of blocks, illustrating thwart in a sentence.

    Thwart means to stop someone from doing what they intended, or to keep a plan from succeeding. To use thwart in a sentence, name the plan and the force that blocks it: “The storm thwarted their attempt to cross.” The verb is transitive and appears most often in the passive voice in news writing.

    Thwart at a glance

    • Thwart is a transitive verb; its forms are thwarts, thwarted and thwarting.
    • It means to stop a plan, attempt or ambition from succeeding.
    • The dominant pattern is thwart + a plan or attempt, and the passive be thwarted by is common in reporting.
    • Thwart belongs to news, sport and formal writing rather than everyday conversation.
    • The commonest error is using thwart for something merely delayed rather than defeated.

    What does thwart mean?

    Thwart is a transitive verb meaning to stop an effort from reaching its goal, usually by blocking it at a decisive moment. The Cambridge entry for thwart records this single core sense, and the rows below separate the kinds of thing that get stopped. In every case the attempt has ended, which is what keeps thwart apart from a word such as hinder.

    Sense Plain meaning Example sentence
    Prevent a plan Stop an attempt from succeeding Heavy rain thwarted their picnic plans.
    Block an ambition Keep somebody from reaching a goal Injury thwarted his bid for the title.
    Foil an attack or plot Defeat an opposing move before it lands Guards thwarted the attempt to break in.

    One limitation is worth stating plainly. Thwart says the attempt was stopped, not slowed, and it does not describe an obstacle that was never faced. When progress continues at a lower speed, hinder is the right verb, and when the outcome never began at all, prevent is plainer still.

    How do you use thwart in a sentence?

    Put the plan, attempt or ambition immediately after the verb, and let the blocker enter as the subject or after by. Five patterns cover almost every real sentence, and the passive is the one newspapers use most because it keeps attention on the plan that failed.

    Pattern Example What it signals
    thwart + plan or attempt Bad weather thwarted the rescue. The object is the thing that was stopped.
    thwart + ambition or goal Injury thwarted her Olympic dream. The object is a hoped-for outcome.
    be thwarted by + cause The launch was thwarted by a last-minute fault. Passive, which foregrounds the cause in reporting.
    thwart + person + in + noun They thwarted him in his ambition. An older, more formal way to name the person.
    thwart + attempt Police thwarted an attempt to break into the depot. The standard opening of a crime report.

    Where an opposing scheme is beaten, foil a plot is the close synonym writers reach for, and where the outcome never began, prevent is simpler than thwart.

    Cartoon cards show a small plan sheet and a stop sign slotting together to model the object pattern of thwart.
    The thing blocked comes straight after thwart, or the sentence turns passive with thwarted by.

    Thwart in a sentence: examples across contexts

    The nine sentences below keep the same verb while changing the plan that fails. Each row names the plan and the force that stopped it, which is the pair thwart always needs.

    Context Example sentence Why this works
    Classroom A broken projector thwarted the class presentation. A small everyday obstacle makes the verb concrete.
    Workplace email The supplier strike thwarted our plans to ship on Friday. Names the cause and the plan in one clause.
    News report Customs officers thwarted an attempt to smuggle the goods. Matches the standard crime-report opening.
    Legal writing The injunction thwarted the developer’s bid to build. A formal order is the force that blocks the plan.
    Sports report A stubborn defence thwarted every attack in the second half. The blocking force is collective and repeated.
    Academic prose Poor funding thwarted the survey before it could start. The cause is structural rather than personal.
    Travel Heavy snow thwarted our journey over the pass. The plan is a journey and the blocker is weather.
    History essay A rival alliance thwarted the king’s plan to expand east. Sets ambition against a named opposing force.
    Conversation The traffic completely thwarted my plan to be early. Casual use keeps the verb but lightens the tone.

    Notice how often the sentence is passive, as in the launch was thwarted. The passive suits thwart because the reader usually cares more about the plan that failed than about the force that stopped it.

    Thwart vs foil, hinder and prevent

    Thwart overlaps with three verbs of obstruction and is interchangeable with none of them. Foil is close but leans toward defeating a scheme, hinder means slowing, and prevent means stopping before anything starts. The table separates the four by how complete the blockage is.

    Attribute thwart foil hinder prevent
    Core meaning Stop a plan from succeeding Defeat an opposing scheme Slow progress down Keep something from starting
    Completeness Complete Complete Partial Complete, before the start
    Typical object A plan, attempt or ambition A plot or plotter Progress or movement An event or outcome
    Typical example The fault thwarted the launch. They foiled the robbery. Rain hindered the search. Vaccines prevent disease.
    Register Journalistic and formal Formal and literary Neutral Neutral

    Verdict: use thwart when a plan was underway and got stopped, foil when an opponent’s scheme was beaten, hinder when progress merely slowed, and prevent when nothing had begun. A problem that leaves everyone stuck rather than defeated calls for stymie instead.

    Word forms and grammar of thwart

    Thwart inflects regularly, and its past participle is the form that dominates news headlines. The table also notes the older senses of the word, which survive in ships and in old poetry but not in ordinary prose. The participle thwarted is the one learners meet first.

    Form Part of speech Example
    thwart verb, base form Nothing will thwart their plan.
    thwarts verb, third person singular A single fault thwarts the whole launch.
    thwarted verb, past and past participle The attempt was thwarted within minutes.
    thwarting verb, present participle They succeeded in thwarting the raid.
    thwart noun, technical The rower shifted on the thwart.
    thwart adverb, archaic Old verse still uses thwart for across.

    The noun thwart, meaning a rower’s seat, and the archaic adverb meaning across are unrelated to most modern uses, so a sentence about being stopped should keep to the verb sense.

    Common mistakes with thwart

    • Incorrect: The rain thwarted the match for an hour. Correct: The rain delayed the match for an hour. Rule: Thwart means stopped, so it cannot describe a pause that later ends.

    • Incorrect: The delay thwarted. Correct: The delay thwarted our plans. Rule: Thwart is transitive, so the plan that failed must appear.

    • Incorrect: The goal thwarted the goalkeeper. Correct: The goalkeeper thwarted the attack. Rule: The blocker is the subject and the plan is the object, not the reverse.

    Practice using thwart

    Work through the six items, then check the reasoning rather than only the answer.

    1. Fill the gap: A last-minute technical fault ______ the rocket launch.
    2. Choose the better word: Roadworks (thwarted / hindered) traffic all morning without stopping it.
    3. Correct the error: The alarm thwarted the thieves from entering.
    4. Build a sentence: use be thwarted by about a picnic ruined by rain.
    5. Spot the register: which belongs in a news report — Officers thwarted a planned robbery, or The cops totally stopped a robbery plan?
    6. Rewrite with a synonym: replace thwart in They thwarted the plot with foil.

    Answers

    1. thwarted — the fault stopped the launch completely, which is the core sense.
    2. hindered — traffic continued slowly, so the blockage was partial.
    3. The alarm thwarted the thieves’ attempt to enter — thwart takes a noun object, not from plus a verb.
    4. Model answer: The picnic was thwarted by a sudden downpour.
    5. Officers thwarted a planned robbery — a report uses neutral words and the standard crime-report verb.
    6. They foiled the plot — foil suits a scheme that was defeated.

    The bottom line

    Use thwart in a sentence when a plan was already underway and something stopped it from succeeding, and put that plan straight after the verb. Two nuances decide most sentences. Thwart means stopped rather than slowed, so hinder is the word for a delay, and the passive be thwarted by suits news writing because it foregrounds the failed plan.

    A cartoon single scene contrasts a plan stopped by a wall with a plan crawling slowly over bumps, showing thwart against hinder.
    Thwart means the attempt ended; hinder means it is still going, just slower.

    Frequently asked questions about thwart

    Is thwart always negative?

    Thwart usually reports a setback, so it is negative for whoever had the plan. The sentence itself stays neutral, which is why it suits news reporting: officers thwart a robbery, and the thief is the one whose plan failed. The word simply records that an attempt did not succeed.

    How do you pronounce thwart?

    Thwart is pronounced to rhyme with short and sport, with a silent-looking w that is not heard at all. The vowel is the same long aw sound as in water. Because the spelling looks hard, learners often add the w, but the standard pronunciation drops it completely.

    What is the past tense of thwart?

    The past tense and past participle are both thwarted. The attempt was thwarted last night uses it in the passive, and heavy snow thwarted the search uses the same form in the active. The regular ending means there is no irregular form to memorise.

    Can thwart be used in the passive?

    Yes, and the passive is very common because readers usually care about the plan that failed. The launch was thwarted by a fault names the cause after by, while the active version puts the cause first. Both are correct, so choose whichever keeps the important thing in focus.
