Surreptitious is an adjective meaning done quietly and secretly to avoid being noticed. To use surreptitious in a sentence, place it before the noun it describes: “She made a surreptitious exit through the side door.” It usually modifies a brief act, such as a glance, a movement or a purchase.
Surreptitious at a glance
- Surreptitious is an adjective; its adverb is surreptitiously and its noun is surreptitiousness.
- It describes one act done to escape notice, never a lasting habit.
- The noun after it is usually glance, look, movement, exit, purchase or recording.
- It belongs to formal and literary writing; in speech people say sneaky or quick.
- The commonest error is using surreptitious for a person, where secretive fits.
What does surreptitious mean?
Surreptitious is an adjective meaning done secretly and quietly so as not to be noticed. The Cambridge entry for surreptitious records this single sense, and the word attaches to acts rather than to people. A surreptitious glance lasts a second; a secretive colleague hides things for years. Where the secrecy is planned rather than momentary, clandestine arrangements is the closer adjective, because clandestine implies an organised plan.
| Shade | What it adds | Example sentence |
|---|---|---|
| Brief and unnoticed | The act lasts only moments | He took a surreptitious photo of the timetable. |
| Deliberately hidden | The person avoids being seen doing it | She cast a surreptitious glance at her phone. |
| Not necessarily wrong | Motive stays neutral | The children made surreptitious signals across the hall. |
One limitation matters. Surreptitious is not a synonym for dishonest, and it says nothing about motive. A surreptitious act can be harmless, such as slipping a note to a friend, so the adjective describes the manner of an action rather than its morality.
How do you use surreptitious in a sentence?
Surreptitious normally sits directly before the noun it describes, and that noun names a short act. Four patterns cover almost every real sentence; the adverb shifts attention from the act to the way it was carried out.
| Pattern | Example | What it signals |
|---|---|---|
| surreptitious + noun | He gave a surreptitious wave from the doorway. | The act itself is hidden from view. |
| a surreptitious + noun | She made a surreptitious copy of the file. | Counts one discreet, countable act. |
| verb + surreptitiously | They surreptitiously passed the note along the row. | Emphasises how the action was performed. |
| noun + be + surreptitious | The handover was surreptitious and fast. | States that a whole event was secretive. |
A writer who wants to stress that something was physically hidden chooses concealed from view, because concealed describes position while surreptitious describes the manner of an act.

Surreptitious in a sentence: examples across contexts
Surreptitious keeps one meaning but changes tone as it moves between registers. The nine sentences below move from a classroom to a news report, and each names the small act being hidden.
| Context | Example sentence | Why this works |
|---|---|---|
| Classroom | Maya passed a surreptitious note to her neighbour during the test. | A concrete act supplies a scene a reader can picture. |
| Workplace email | He made a surreptitious check of the figures before the meeting. | The noun check names one quiet, countable action. |
| News report | The reporter obtained a surreptitious recording of the call. | Pairs the adjective with recording, its most formal noun. |
| Legal writing | The tenants made a surreptitious entry to inspect the damage. | The act sense fits a precise, factual account. |
| Science writing | Researchers took surreptitious samples from the nest at night. | Keeps the observer hidden without implying wrongdoing. |
| Travel writing | We stole a surreptitious look at the palace gardens. | The idiom steal a look supports the adjective naturally. |
| Academic prose | The diary offers a surreptitious view of court life. | Extends the sense from an act to a hidden perspective. |
| Sports commentary | The captain threw a surreptitious glance at the bench. | One gesture conveys a plan kept from opponents. |
| Conversation | I had a surreptitious peek at the answers. | Survives in speech with the light noun peek. |
Only the news and legal rows use a fully formal noun. That shift in noun choice, not the adjective itself, is what signals the register.
Surreptitious vs secretive
Surreptitious and secretive both describe concealment, but they attach to different things. secretive describes a person or group with a lasting habit of hiding information; surreptitious describes one act carried out quietly.
| Attribute | surreptitious | secretive |
|---|---|---|
| What it describes | A single act | A person or organisation |
| Duration | Seconds or minutes | An ongoing pattern |
| Typical noun | Glance, movement, recording | Person, family, committee |
| Implies a plan | No, only a wish to avoid notice | Yes, a sustained policy of concealment |
| Register | Formal and literary | Neutral to formal |
Verdict: call one hidden action surreptitious, and call the person who keeps hiding things secretive.
Word forms and grammar of surreptitious
Surreptitious changes form regularly, and the adverb surreptitiously is the form writers reach for when they want to describe how an action was done. The table also lists a form learners invent by mistake.
| Form | Part of speech | Example |
|---|---|---|
| surreptitious | adjective | She gave a surreptitious nod. |
| surreptitiously | adverb | He surreptitiously opened the drawer. |
| surreptitiousness | noun, rare | The surreptitiousness of the visit surprised them. |
| surreptition | non-standard noun | Do not write surreptition; the noun is surreptitiousness. |
The adjective has no comparative form, so a writer says more surreptitious rather than surreptitiouser, and the adverb cannot be replaced by an adjective in a verb phrase.

The bottom line
Use surreptitious in a sentence when one quiet act is done to avoid being noticed, and place it directly before the noun for that act. Two nuances decide most sentences: the word describes an action rather than a person, so a lasting habit needs secretive instead, and it carries no judgement of motive, so it can label harmless concealment as easily as a serious one. Where something is physically hidden, a furtive movement is often the more precise choice.

Frequently asked questions about surreptitious
Is surreptitious a formal word?
Surreptitious belongs to formal and literary writing, where it usually modifies an act such as a glance or a recording. Everyday speech tends to prefer sneaky, quick or a quick look. A text message saying I had a surreptitious peek is possible, but a news report is where the adjective feels most at home.
Does surreptitious suggest something illegal?
No. Surreptitious describes the manner of an act, not its legality, so it can label something harmless such as hiding a birthday present. The word says only that the action was done quietly to avoid notice. If a sentence needs to signal wrongdoing, a word such as stealthy or underhanded carries that judgement.
Can a person be described as surreptitious?
A person can be, but the sentence usually reads better with secretive. Surreptitious is reserved for a single act, so a surreptitious visitor suggests one quiet visit, while a secretive visitor suggests a lasting habit of hiding things. Choose secretive when the concealment is a pattern rather than a moment.
What is the adverb form of surreptitious?
The adverb is surreptitiously, and it modifies a verb rather than a noun. Writers use it when the way an action was performed matters more than the act itself, as in he surreptitiously opened the drawer. The adjective would be wrong there, because it cannot describe how a verb happened.
