Frivolous in a Sentence: Meaning, Examples & Practice

    Cartoon pupils crowd a shop counter buying novelty toys instead of a class microscope, showing a frivolous purchase in a sentence.

    Frivolous describes something that lacks seriousness, weight or good sense. To use frivolous in a sentence, place it before the noun it judges: “a frivolous complaint” or “a frivolous purchase.” The adjective carries a hint of disapproval, so it suits writing about spending, objections and behaviour more than neutral description.

    Frivolous at a glance

    • Frivolous is an adjective; its derived forms are the adverb frivolously and the nouns frivolity and frivolousness.
    • The core sense is a lack of seriousness, so it usually judges spending, objections, remarks or behaviour.
    • Attributive use (a frivolous claim) is far more common than predicative use (the claim was frivolous).
    • Its commonest collocations are frivolous lawsuit, frivolous spending, frivolous remark and frivolous pleasure.
    • The commonest error is treating frivolous as a warm synonym for fun; it actually signals waste or poor judgement.

    What does frivolous mean?

    Frivolous is an adjective meaning not serious, sensible or worth serious attention. The Cambridge entry for frivolous separates two strands: a light, playful attitude, and a thing too unimportant to deserve effort. The word also has a legal life, where a frivolous claim is one brought without any real basis. Where the mood is innocent and cheerful rather than wasteful, carefree and light-hearted is the fairer word, because frivolous always keeps a note of criticism.

    Sense Plain meaning Example sentence
    Light and unserious Behaviour that refuses to be serious Their frivolous jokes broke the tension in the staffroom.
    Too unimportant to matter A detail or amount with no real weight The auditor ignored the frivolous difference of two pence.
    Legally baseless A claim brought with no proper ground The tribunal threw out the frivolous complaint in a single morning.

    One limitation is worth stating plainly. Frivolous is a judgement, not a measurement. A purchase can be modest and still frivolous, and an expensive one can be perfectly sensible, so the word reports the writer’s view of its purpose rather than its price. It never means simply cheap, and it never means fun.

    How do you use frivolous in a sentence?

    The adjective attaches to the thing being judged, and the verb that introduces it often does the dismissing. Five patterns cover almost every real sentence, and the attributive one is the workhorse of formal writing.

    Pattern Example What it signals
    frivolous + noun A frivolous objection delayed the vote. The writer judges the thing as not worth serious attention.
    linking verb + frivolous The application was frivolous. States the judgement directly, common in legal and formal prose.
    more / most frivolous The second appeal was even more frivolous than the first. Ranks two things by how little weight they deserve.
    treat or dismiss as frivolous The chair dismissed the point as frivolous. Reports how one person judged another’s contribution.
    verb + frivolously The committee spent frivolously on catering. Describes the manner of an action rather than the thing itself.
    A word card clicks into a board slot directly in front of three picture cards, showing where frivolous sits in a sentence.
    The adjective usually attaches to a noun, as in a frivolous complaint or a frivolous objection.

    Frivolous in a sentence: examples across contexts

    Frivolous keeps its judgement as it moves between registers, but the thing being judged changes. The nine sentences below shift from a classroom to a tribunal, and each one names what is being called unworthy of serious effort.

    Context Example sentence Why this works
    Classroom The class spent the trip fund on a frivolous mascot instead of the museum tickets. A concrete purchase shows the word judging a wasteful choice.
    Workplace email Please confirm that no frivolous expenses were claimed during the conference. The formal register fits a written internal instruction.
    News report The mayor dismissed the recall petition as a frivolous stunt. Reports how a public figure judged an opponent’s action.
    Legal writing Costs may be awarded when a party makes a frivolous application. Uses the technical sense: no proper legal basis.
    Conversation We bought a frivolous ice-cream machine and have used it twice. The first person and the light tone show the word works in speech.
    Academic writing The study set aside what it called the frivolous question of colour preference. Signals that a line of enquiry was judged not serious.
    Performance review A pattern of frivolous leave requests affected the whole team. Ties the adjective to a repeated behaviour rather than one act.
    Council meeting Residents said the new fountain was a frivolous use of public money. Names who is making the judgement, which is typical of civic debate.
    Advertising critique The campaign promised nothing beyond a frivolous slogan. Dismisses the work by attacking its seriousness, not its cost.

    Frivolous vs trivial

    Frivolous and trivial both shrink a thing, but they shrink different things. Frivolous attacks seriousness and good sense; trivial attacks size and importance. Flippant is a close cousin, but it judges the tone of flippant answers rather than the waste in an action.

    Attribute frivolous trivial
    Core meaning Without seriousness or good sense Small, unimportant, of little value
    What it judges Motive, propriety or seriousness Size, importance or difficulty
    Typical collocations frivolous lawsuit, frivolous spending trivial detail, trivial matter
    Strength Stronger; implies criticism of waste Milder; implies the thing merely does not matter
    Register Formal, legal and journalistic as well as everyday Neutral and everyday across all registers
    Describing a person Can describe a person’s manner or attitude Rarely describes a person directly

    Verdict: use frivolous when something shows a lack of seriousness or good judgement, and use trivial when the point is only that something is small and unimportant. When the point is only that something is trivial or minor, the milder adjective is the honest choice.

    Practice using frivolous

    Work through the six items, then check the reason rather than only the key.

    1. Fill the gap: The auditor removed the ______ items from the budget because they had no useful purpose.
    2. Choose the better word: The children were (carefree / frivolous) as they paddled in the cold sea.
    3. Correct the error: The board rejected the proposal frivolous.
    4. Build a sentence: use frivolous spending about a club that bought a golden statue.
    5. Spot the register: which belongs in a formal complaint to a council — the new clock is a frivolous waste of funds, or the new clock is such a silly waste of money?
    6. Rewrite with the noun: The whole plan seemed frivolous. Use frivolity instead.

    Answers

    1. frivolous — the items had no useful purpose, which is exactly what the adjective judges.
    2. carefree — paddling in the sea is harmless fun, so the word must not carry criticism.
    3. The board rejected the proposal as frivolous — the adjective needs a linking verb or the word as before it.
    4. Model answer: The club’s frivolous spending on a golden statue emptied the accounts.
    5. The new clock is a frivolous waste of funds — a formal complaint keeps the register and drops the word silly.
    6. The whole plan had an air of frivolity — the noun takes an article and replaces the adjective.

    The bottom line

    Use frivolous in a sentence when you want to judge something as lacking seriousness or good sense, and let the surrounding words supply the detail. The two points that decide most sentences are these: the word carries built-in criticism, so it can never simply mean cheerful, and the legal sense applies the same idea in a stricter, more costly setting. For a quality that is shallow rather than wasteful, superficial charm is the better term.

    A cartoon single continuous scene contrasts a child buying a pointless toy with a child joking during a quiet assembly.
    Frivolous targets wasted purpose, while flippant targets the manner of a remark.

    Frequently asked questions about frivolous

    Is frivolous always a criticism?

    Frivolous nearly always carries disapproval, because it says something lacks seriousness or good sense. Even the lighter sense, a frivolous remark, hints that the speaker should have been more serious. If you want to describe innocent fun without blame, use carefree, playful or light-hearted instead, and keep frivolous for choices you are judging.

    What is the noun form of frivolous?

    Frivolous is an adjective, so it cannot follow an article directly. Its two nouns are frivolity, which is the more common and more literary choice, and frivolousness, which is clumsier but equally correct. Write the frivolity of the scheme, never the frivolous of the scheme.

    Can frivolous describe a person?

    Yes, but it describes a person’s manner or attitude rather than the person as a whole. A frivolous young man behaves without seriousness, while a trivial person is rare because trivial usually describes things. The adjective keeps the same meaning whether it points at a person, an action or a claim.

    What is a frivolous lawsuit?

    In legal writing, a frivolous lawsuit is a case brought without any reasonable basis, so it wastes the court’s time. Judges can impose costs on the party who filed it. The phrase keeps the general meaning of frivolous, but here the lack of seriousness has a precise legal consequence.


    Have you ever heard of the word “frivolous” and wondered what it meant? In essence, “frivolous” refers to something that is not serious, important, or sensible, often characterized by a lack of purpose or value.

    These frivolous actions, statements, or decisions are often viewed as trivial or unimportant in nature, lacking depth or significance. When labeling something as frivolous, it suggests that it is done in a light-hearted or whimsical manner, without much thought or consideration.

By prioritizing clarity and coherence in our writing and speech, we can effectively convey our ideas and engage our audience in a more meaningful manner.
