1.nounA2
Definition

the flat surface created by the top of your thighs when you sit down, where you can rest objects, a book, a child, or a pet

Example

The little girl sat quietly on her mother's lap while the story was being read.

on someone's lap

Bao balanced a bowl of noodles on his lap and ate dinner while watching television.

on his lap — holding an object

Synonyms
  • thighs

    refers to the upper legs themselves, not the flat surface formed when sitting

  • knees

    sometimes used informally instead of 'lap' when someone is sitting on another person — e.g. 'sit on my knees' but technically less accurate

Usage Note

This sense is typically used with a possessive ('his lap', 'her lap') or in the phrase 'on someone's lap'. It is rarely used without a reference to a person.

Common Mistakes

The book is on the lap.
The book is on my lap.
In English, 'lap' almost always needs a possessive or a reference to whose lap it is, because the lap is part of a specific person's body.

2. a single circuit of a marked course that competitors travel around more than onc

2.nounB1
Definition

a single circuit of a marked course that competitors travel around more than once to decide the result of a race

Example

The Formula One driver finished the final lap three seconds faster than his nearest rival.

final lap — race context

With only two laps to go, the leading runner began to slow down from exhaustion.

laps to go

Synonyms
  • circuit

    more formal, often used for the complete course itself rather than one trip around it

  • round

    used in boxing, golf, and some sports for a unit of play; broader than 'lap'

  • leg

    one section of a longer race or journey, often in relays or multi-stage events

Common Mistakes

I ran ten laps in the gym.
I ran ten laps around the track.
'Lap' is specifically for a circuit with a clear start and end point. A treadmill or gym exercise is not a 'lap' unless it follows a circuit.

3. a celebratory circuit of the playing area that the victor of a competition compl

3.nounB2
Definition

a celebratory circuit of the playing area that the victor of a competition completes to share the win with the audience

Example

After winning the hundred-metre race, Elena took a victory lap and waved to the cheering crowd.

victory lap

The home team ran a lap of honour around the stadium while the supporters sang the club song.

lap of honour

Synonyms
  • victory lap

    the most common term for this celebration run

  • lap of honour

    the British English equivalent, equally common in the UK

Usage Note

Commonly called a 'victory lap' or 'lap of honour'. The phrase 'lap of honour' is more common in British English. This sense is distinct from sense 2 (a regular race lap) because its purpose is celebration, not competition.

4. one distinct part within a longer trip, a series of tasks, or a broader activity

4.nounB2
Definition

one distinct part within a longer trip, a series of tasks, or a broader activity, treated as a separate portion

Example

The first lap of our road trip took us from Taipei all the way down to Kaohsiung.

lap of a journey

We have completed the design lap of the project and are ready to start building the prototype.

lap of a project

Synonyms
  • stage

    the general term for a distinct phase; 'lap' adds a sense of returning to a starting point

  • phase

    more formal than 'lap', used in project management and planning

  • leg

    specifically used for stages of a journey or race, very close in meaning to this sense

Usage Note

This sense is used figuratively, extending the racing metaphor to non-competitive contexts like work, travel, or any step-by-step process. It is less common in everyday speech than senses 1 and 2.

Common Mistakes

I finished the first lap of reading the book.
I finished the first chapter of the book.
'Lap' for a stage of work is appropriate only when the work naturally divides into repeated rounds or circuits. Reading a book chapter by chapter is not a 'lap'.

5. a part of something, especially cloth, paper, or material, that folds over or li

5.nounC1
Definition

a part of something, especially cloth, paper, or material, that folds over or lies on top of another part, or a loose piece that hangs down

Example

The tailor carefully stitched the lap of the jacket lining so that it lay perfectly flat.

lap of a garment

There was a small lap of extra paper at the edge of the envelope that needed to be folded in.

Synonyms
  • flap

    a loose piece attached at one edge, more common in everyday language than 'lap' in this sense

  • overlap

    emphasises where one part covers another rather than the part itself

  • fold

    a line or area where material is bent back on itself

Usage Note

This sense is mostly used in sewing, tailoring, and crafts. It is the original historical meaning from which the 'upper legs' sense developed — the idea of a fold or flap. Modern speakers rarely encounter this use outside of technical contexts.

Synonym discussion

Sense: noun/2

In racing contexts, 'lap' refers specifically to one complete trip around a defined track or course — it is the most concrete and common word for this idea. 'Circuit' can mean the same thing but often refers to the entire track layout itself ('a three-kilometre circuit') rather than one trip around it. 'Round' is broader: it is used in boxing for a timed segment of a fight, in golf for a full set of 18 holes, and in multi-stage competitions for each phase of elimination — it does not imply a circular course. 'Leg' is narrower: it refers to one section of a multi-stage race or journey where the start and end points are different, not a closed loop. For example, a runner might say 'I completed the first leg of the relay' but not 'the first leg around the track'. Use 'lap' when the course returns to its starting point; use 'leg' when the race moves from point A to point B.

Etymology

Old EnglishGermanicEnglish

The word 'lap' comes from Old English 'læppa', meaning a fold or flap of a garment — the part that hangs loose or overlaps another part. This original meaning survives in modern uses like 'overlap' and in tailoring. By the 1300s, the word had come to mean the area from waist to knees formed when a person sits (the fold of the body). The racing sense developed in the 1800s, based on the idea of a circuit that folds back on itself. The animal-drinking sense is unrelated and comes from Old English 'lapian', which imitates the sound of lapping water.
