Slip Meaning: Definition, Uses and Examples
Slip is one of the busiest small words in English. It is a verb, a noun, and the start of a dozen common phrases — and its meanings all grow from a single image: something moving smoothly, quickly, and usually out of control. A foot slips on ice. A secret slips out. A name slips your mind. Standards slip. Each sense is a different thing sliding away from where it should be, and that shared idea is what holds the word together.
Because slip does so much work, learners meet it in confusing places: a slip of paper has nothing to do with falling over, and a slip of the tongue is not about feet at all. This article takes the senses in order of usefulness — the ones you will actually meet first — and marks the rare ones clearly as rare.

“Slip” as a Verb: The Three Main Senses
1. To slide accidentally (the commonest sense)
This is the sense everyone knows first. To slip is to slide without intending to, usually losing your footing or your grip:
- “I slipped on the wet floor and fell.”
- “The plate slipped out of her hands.”
- “Her foot slipped off the pedal.”
The key word is accidentally. Sliding on purpose is not slipping — a child slides down a slide, but a walker slips on ice. The accident is part of the meaning.
2. To move quickly and quietly
The second sense is about speed and stealth rather than falling. To slip somewhere is to go there quickly, often so that nobody notices:
- “She slipped out of the meeting before it ended.”
- “He slipped the note into her bag.”
- “I need to slip into town before lunch.”
Notice the prepositions: you slip out of a room, slip into a coat, slip away from a crowd, slip past a guard. The word suggests lightness — no fuss, no noise, no announcement. It is the verb of the quiet exit, and it is usually neutral or even admiring.
3. To get worse, to decline
The third sense is figurative, and it is everywhere in news and business English. To slip is to move gradually into a worse state:
- “Standards have slipped since last year.”
- “House prices slipped by two per cent.”
- “I must be slipping — I forgot her name again.”
- “His attention slipped during the long meeting.”
Here the image is the same — something sliding out of position — but the thing sliding is a standard, a price, a memory, or a performance. The decline is usually gradual and often unnoticed until pointed out. A fall is sudden; a slip is a slow slide, and that is how most declines actually happen.
“Slip” as a Noun: The Senses You Will Meet
A small mistake
The commonest noun sense is a small, usually spoken or written mistake: “It was just a slip — no need to apologise.” The phrase a slip of the tongue means a small spoken error, saying the wrong word by accident. A Freudian slip is a special case: a mistake in speech that supposedly reveals a hidden thought or feeling. The term comes from Sigmund Freud, who argued that such slips were not random; whether you believe the theory or not, the phrase always means a revealing mistake, not an ordinary one.
A small piece of paper
A slip is also a small piece of paper, usually with something written on it: “a slip of paper,” “a betting slip,” “a payslip,” “a permission slip.” The idea is a small, thin piece, torn or cut from a larger sheet. A payslip shows what you were paid; a betting slip records a bet; a permission slip is the form a parent signs to allow a school trip.
An act of slipping
The noun can also name the act itself: “Her sprained ankle was the result of a slip on the path.” It appears most often in reports of accidents — “a slip on the stairs,” “a slip on wet leaves.” Safety language uses slips, trips and falls as a set phrase, and the distinction is precise: a slip is losing footing on a slippery surface, a trip is catching your foot, and a fall is the result of either.
Rarer noun senses
A few senses are worth recognising even though you will rarely need them. A slip is a light undergarment, like a dress or skirt, worn under clothes — an older word now, mostly seen in period novels. In cricket, slip is a fielding position beside the wicketkeeper — “first slip,” “second slip.” In boatbuilding, a slip (or slipway) is a sloping platform for launching ships. And in pottery, slip is liquid clay used for decorating or joining pieces.
How to Pronounce “Slip”: UK and US
- UK: /slɪp/ — SLIP
- US: /slɪp/ — SLIP
One syllable, pronounced identically in British and American English: the i is the short vowel of sit and lip, and the word rhymes with clip, flip, and trip. The past tense and past participle are both slipped, with the p doubled — slip, slipped, slipped. Writing “sliped” with one p is the commonest spelling error with this word.
Slip vs Slide vs Trip
Three words for losing control of your feet, three different meanings:
| Word | Meaning | Example |
|---|---|---|
| slip | To slide accidentally on a smooth or wet surface; to lose your footing. | “She slipped on the icy pavement.” |
| slide | To move smoothly along a surface, usually on purpose. | “The children slid down the banister.” |
| trip | To catch your foot on something and stumble. | “He tripped over the rug.” |
The test is the cause. If the surface was slippery, you slipped. If your foot caught on something, you tripped. If you moved smoothly and meant to, you slid. The distinction matters in accident reports, insurance claims, and safety signs — and it is one of the few places where choosing the right word is genuinely practical rather than merely correct.
Common Phrases With “Slip”
| Phrase | Meaning |
|---|---|
| slip away | To leave quietly, or to pass away (of time, or of a person dying peacefully): “The afternoon slipped away.” “He slipped away in his sleep.” |
| slip up | To make a mistake: “I slipped up and sent the email to the wrong person.” The noun form is a slip-up. |
| let slip | To reveal something accidentally: “She let slip that she was leaving.” |
| slip one’s mind | To be forgotten: “It completely slipped my mind.” |
| slip through one’s fingers | To escape or be lost through carelessness: “The chance slipped through his fingers.” |
| slip of the tongue | A small spoken mistake: “It was just a slip of the tongue.” |
| slip into / out of | To put on or take off quickly (clothes), or to enter or leave quietly: “She slipped into her coat.” “He slipped out of the room.” |
These phrases are why slip is worth learning as a whole word, not a single definition: “it slipped my mind” is far more common in conversation than the falling sense.
How to Use “Slip” in a Sentence
- “Careful — the floor is wet, and you might slip.”
- “She slipped the letter under the door and walked away.”
- “His grades began to slip in his final year.”
- “It was only a small slip; nobody noticed.”
- “Write your name on a slip of paper and put it in the box.”

Common Mistakes
Spelling the past tense “sliped.” The past tense is slipped, with a double p. The rule is regular: a short verb ending in one consonant after a short vowel doubles the consonant before -ed.
Using “slip” for a deliberate slide. Sliding is controlled; slipping is accidental. A child slides down a slide. A walker slips on ice. Mixing them up changes the meaning from play to accident.
Confusing “slip” and “trip.” You slip on ice and trip over a rug. The cause — slippery surface or caught foot — decides the word.
Calling any mistake a slip. A slip is a small mistake, usually made by accident. A serious error of judgement is not a slip, and calling it one sounds like an excuse.

Learn the three verb senses — slide accidentally, move quickly and quietly, get worse — and the noun senses — a small mistake, a small piece of paper. Spell the past tense with two ps (slipped), keep it apart from slide and trip, and remember that a slip is always small and almost always an accident.
