  • fittedpast simple
  • fitpast simple
  • fitting-ing form

1. When an object fits a particular space or opening, it has the right measurements

1.verbtransitive / intransitiveB1
Definition

When an object fits a particular space or opening, it has the right measurements to go into that space — not too big, too wide, or too tall to enter.

Example

Ishmael checked whether the suitcase would fit into the overhead compartment on the plane.

fit + into + [physical space]

The sofa could not fit through the apartment door, so the team took it back to the store.

fit + through + [narrow opening]

Common collocations
  • fit into
  • fit through
  • fit in
  • fit on
  • fit under
Synonyms
  • go into

    less formal, used in spoken English

  • enter

    more formal, not typically used for objects fitting into tight spaces

Grammar Patterns

fit + [space/opening]

fit + into/through/in/on + [space]

Usage Note

Commonly used with prepositions that describe direction or position: into, through, in, on, under. The transitive form (fit + object) most often appears with lock, socket, slot, or opening.

Common Mistakes

The suitcase doesn't fit in the car trunk because the trunk is too big.
The suitcase doesn't fit in the car trunk because the trunk is too small.
'doesn't fit' means the object is too large, not that the space is too large for an object that's bigger.

2. To place a thing or person into a space where there is enough room for them, or

2.verbtransitiveB1
Definition

To place a thing or person into a space where there is enough room for them, or to have enough capacity to contain a certain number.

Example

We can fit four people in the back seat if the children sit in the middle.

fit + [number of people] + in + [location]

Hoa fitted the camping gear into the trunk before leaving for the weekend trip.

Common collocations
  • fit in
  • fit into
  • fit on
  • fit up to
Synonyms
  • accommodate

    more formal, used for capacity rather than physical placement

  • squeeze in

    informal, suggests a tight or difficult placement

  • make room for

    phrase, emphasises creating space rather than using existing space

Grammar Patterns

fit + [person/thing] + [preposition + location]

fit + [number] + [people/things] + in/into

Usage Note

When used for scheduling (fit someone in), the object is always a person and the context is a busy timetable. The capacity sense (fit twelve passengers) is always followed by a number and refers to maximum capacity.

3. When you say an item of clothing fits, it means the garment's dimensions match y

3.verbtransitive / intransitiveA2
Definition

When you say an item of clothing fits, it means the garment's dimensions match your body measurements properly — not too tight, loose, long, or short in any area.

Example

The blue jacket fits me perfectly across the shoulders, but it is a little tight around the waist.

fit + [person] + across/around + [body part]

Élise tried on three dresses at the store before finding one that actually fit.

intransitive: [clothing] + fit

Common collocations
  • fit well
  • fit perfectly
  • fit tightly
  • fit loosely
  • fit across
  • fit around
Synonyms

Grammar Patterns

fit + [person]

fit + adverb (well/perfectly/tightly)

[clothing] + fits

Usage Note

Unlike sense 1 (object entering a space), this sense always involves a person's body. The subject is always an item of clothing, shoe, or wearable accessory. Passive forms (be fitted for) exist in tailoring contexts: 'He was fitted for a new suit.'

Common Mistakes

The jacket fits to me.
The jacket fits me.
No preposition is needed; fit is used directly with the person.

4. To be so precisely the right size and shape that there is no extra space, loosen

4.verbintransitiveB1
Definition

To be so precisely the right size and shape that there is no extra space, looseness, or movement between the object and what it goes into or onto.

Example

The dress fits her like a glove — the tailor did a wonderful job with the alterations.

idiomatic: fit + like a glove

The round lid fits snugly over the container, keeping the food fresh for days.

fit + snugly + over

Common collocations
  • fit perfectly
  • fit snugly
  • fit exactly
  • fit like a glove
  • fit tightly
Synonyms
Antonyms

Grammar Patterns

fit + adverb (perfectly/snugly/well)

fit + like a + [noun]

Usage Note

This sense intensifies sense 3 (CLOTHING SIZE) and sense 1 (FIT INTO SPACE) by adding the idea of zero tolerance — no looseness, no gap. It is often used with adverbs like perfectly, snugly, exactly, or with the fixed idiom fit like a glove.

5. To be appropriate, acceptable, or well-matched to a particular situation, purpos

5.verbtransitive / intransitiveB1
Definition

To be appropriate, acceptable, or well-matched to a particular situation, purpose, need, or description — so that a thing or person suits the context it is used in.

Example

Her calm and steady voice fits the serious mood of the ceremony very well.

fit + [mood/atmosphere]

The punishment should fit the crime in any fair system of justice.

fixed phrase: fit the crime

Common collocations
  • fit the description
  • fit the crime
  • fit the bill
  • fit someone's needs
  • fit the profile
  • fit the mood
Synonyms
  • suit

    interchangeable in many contexts; 'suit' can also imply visual harmony ('blue suits you')

  • match

    emphasises correspondence between two things

  • be appropriate for

    more formal register

Antonyms

Grammar Patterns

fit + [situation/need/purpose]

fit + [description/profile]

fit + for + [purpose]

Usage Note

Distinguish from sense 1 (FIT INTO SPACE): sense 5 is abstract suitability, never physical dimensions. The fixed phrase 'fit the crime' is common in legal and moral contexts; 'fit the bill' is an informal idiom meaning 'be exactly what is needed'.

Common Mistakes

This job fits to my skills.
This job fits my skills.
No preposition before the object in transitive use.

6. To put a piece of equipment, a device, or a part into its correct position withi

6.verbtransitiveB2
Definition

To put a piece of equipment, a device, or a part into its correct position within something else, typically as a permanent addition or upgrade.

Example

The technician fitted a new smoke alarm in the hallway ceiling last Tuesday morning.

fit + [device] + in/on + [location]

We plan to fit solar panels on the roof next spring to reduce our electricity bills.

Common collocations
  • fit with
  • fit in
  • fit onto
  • be fitted with
  • have something fitted
Synonyms
  • install

    more formal, preferred in American English, emphasises the technical process

  • mount

    used when the item is attached to a wall or surface

  • equip with

    focuses on the provision rather than the physical placement

Antonyms
  • remove

    to take out something that was fitted

Grammar Patterns

fit + [object] + [preposition + location]

be fitted with + [equipment]

have + [object] + fitted

Usage Note

Common in passive constructions (be fitted with) for describing standard features of products. The pattern 'have something fitted' is used when someone else does the installation. In British English, 'fit' is more common for home installations; American English often prefers 'install'.

Common Mistakes

I fitted the new curtains.
I hung the new curtains.
'Fit' is used for equipment, devices, and parts that are fixed in position, not for items that are simply placed or hung.

7. to experience a sudden episode where your body moves uncontrollably, caused by a

7.verbintransitiveB2
Definition

to experience a sudden episode where your body moves uncontrollably, caused by a medical condition such as epilepsy or a very high fever.

Example

Tariro watched helplessly as her younger brother began to fit on the kitchen floor.

bare verb 'fit' used for seizure onset

The nurse noted that three-year-old Sofie had fitted twice during the night.

Synonyms
  • have a seizure

    the standard medical and everyday expression, much more widely understood

  • convulse

    focuses on the physical shaking movements; C1-level vocabulary

Grammar Patterns

fit (no object)

have a fit / have a seizure (more common)

Usage Note

The verb 'fit' in this sense is much less common than the noun phrases 'have a fit' or 'have a seizure'. In everyday speech, most English speakers say 'had a seizure' or 'had a fit' rather than 'fitted'.

Common Mistakes

The child fitted during class' (when describing a seizure).
The child had a fit during class.
The bare verb 'fit' for seizures is uncommon; most speakers use the phrase 'have a fit' or 'have a seizure'.

8. to supply someone with the necessary training, skills, or personal qualities tha

8.verbtransitiveB2
Definition

to supply someone with the necessary training, skills, or personal qualities that make them ready to take on a specific role or type of work — for example, fitting a new recruit for a sales position through intensive training.

Example

The training programme aims to fit new employees for their specific duties.

fit + object + for + noun (active voice)

A good education should fit young people for the challenges of adult life.

modal + fit + object + for + abstract noun

Common collocations
  • fit + object + for + role
  • be fitted for + position
  • well fitted for / perfectly fitted for
Synonyms
  • prepare

    more general and common; 'fit' adds the nuance of making precisely suitable

  • qualify

    specifically gaining official skills or certificates for a job

  • equip

    can be used both literally (with tools) and figuratively (with skills)

Grammar Patterns

fit + noun + for + noun

be fitted for + noun

fit + noun + well / perfectly + for + noun

Usage Note

Common in formal and professional contexts such as job training, education, and career development. The object is typically a person or group, and the preposition 'for' introduces the role or task. Distinguish from sense 5 (verb/5: BE SUITABLE), which describes an existing state of being appropriate, not an active process of making someone ready.

Common Mistakes

This job fits her perfectly' (when meaning the training made her ready).
The training course fitted her for the job perfectly.
'Fit' alone usually describes natural suitability; to express the act of preparing someone, use the pattern 'fit + object + for + role'.

Synonym discussion

Sense: verb/5

Fit, suit, match, and correspond all describe compatibility between two things, but they differ in focus and usage. 'Fit' emphasises that something meets the requirements or dimensions of a situation or need — for example, 'This role fits her skills' or 'The key fits the lock.' 'Suit' is more subjective and often involves personal preference, appearance, or harmony: 'This colour suits you' or 'That time suits my schedule.' 'Match' implies a close or exact correspondence, often visual or quantitative: 'The socks match his shirt' or 'Her story matches the evidence.' 'Correspond' is more formal and abstract, suggesting systematic or structural alignment: 'The two accounts do not correspond.' In practical terms: use 'fit' for suitability to purpose, 'suit' for pleasing compatibility, 'match' for sameness or visual harmony, and 'correspond' for formal equivalence between systems or reports.

Common collocations

Etymology

Old Norse (suitability cluster)Old English (seizure cluster)Middle EnglishEnglish

The word 'fit' has two separate origins that merged in modern English. The meaning cluster around 'suitable,' 'right size,' and 'physically healthy' comes from Middle English fitten (to put in order, to be suitable), borrowed from Old Norse fitja (to knit, to arrange). The unrelated medical/outburst cluster — meaning a seizure or sudden emotional burst — comes from Old English fitt (a struggle, conflict), which later developed into 'a sudden attack of illness' in the 16th–17th centuries. Modern speakers experience 'fit' as one word, but its two historical threads explain why the same word can describe both a well-tailored suit and an epileptic episode.
