Common collocations
  • unlimited data
  • unlimited access
  • unlimited time
  • unlimited power
  • unlimited refills
  • unlimited supply
  • unlimited potential
Synonyms
  • endless

    Focuses on continuous duration rather than quantity — 'endless waiting' suggests it keeps going, not just that there is no cap.

  • limitless

    Very close in meaning, but slightly more poetic or dramatic; 'limitless sky' feels grander than 'unlimited sky'.

  • infinite

    Suggests something so vast it cannot be measured or imagined; more mathematical or spiritual in tone.

  • unrestricted

    Emphasizes the absence of rules or controls rather than quantity — 'unrestricted access' means no permission needed.

Antonyms

    Direct opposite — there is a fixed cap on amount or extent.

  • restricted

    Emphasizes control or rules that limit what you can do.

  • finite

    Has a clear end or boundary; more technical or scientific.

Usage Note

Frequently used with uncountable nouns related to resources or consumption (data, access, time, power, food, refills). Sounds unnatural with individual countable items — 'unlimited apples' is odd, whereas 'unlimited refills of soda' is natural because refills refer to the ongoing service, not the individual items.

Common Mistakes

The amusement park offers unlimited rides after 6 PM.
The amusement park offers unlimited access to rides after 6 PM.
'rides' (countable events) sounds unnatural; pair unlimited with 'access' or a service noun instead.
She has unlimited friends.
She has an unlimited number of followers on social media.
Unlimited does not naturally describe a specific countable set of people; use 'countless' or 'an unlimited number of' instead.

2.adjectiveB2
Definition

If something such as support, trust, or authority is unlimited, it is complete and total — given or offered without any hidden conditions, restrictions, or exceptions.

Example

Eleni told her son he had her unlimited support in any career he chose.

unlimited + support for unconditional commitment

The ambassador was given unlimited authority to negotiate with the other government.

unlimited + authority for formal/legal context

Common collocations
  • unlimited support
  • unlimited trust
  • unlimited love
  • unlimited loyalty
  • unlimited authority
  • unlimited power
Synonyms
  • unconditional

    Stronger emphasis on the absence of conditions; often used with 'love' or 'support'.

  • absolute

    Emphasizes completeness and the idea that nothing can overrule it; 'absolute power' cannot be challenged.

  • unrestricted

    Also works in this sense but focuses on lack of rules rather than lack of conditions.

  • total

    Less formal and more conversational; 'total support' is common in everyday speech.

Antonyms
  • conditional

    Given only if certain conditions are met — the direct opposite.

  • qualified

    Limited or modified by exceptions or reservations.

  • restricted

    Bound by rules or limitations.

Grammar Patterns

unlimited + [abstract noun: support/trust/love/authority]

Usage Note

Restricted to abstract nouns that describe commitment or control: support, trust, love, loyalty, authority, power. Unlike sense 1, this sense cannot describe physical quantities (data, food, time). Distinguish from sense 1 (NO LIMIT) by checking whether the noun is a physical resource — if yes, it is sense 1.

Common Mistakes

The contract gives us unlimited authority to use the office printer.
The contract gives us unlimited access to the office printer.
Using 'authority' for a small physical resource confuses sense 2 (abstract commitment) with sense 1 (quantity/access).

Synonym discussion

Sense: adjective/1

All four words describe something without a clear boundary, but they differ in what kind of boundary is missing. Unlimited most often refers to an imposed cap that has been removed — an unlimited data plan means the company does not stop you after a certain amount. Limitless carries a more sweeping, almost poetic tone: 'the limitless sky' or 'limitless imagination' suggest something that cannot be bounded by definition. Endless focuses on time or repetition — an endless meeting drags on, and endless opportunities keep appearing one after another. Infinite belongs to mathematics and philosophy — it describes something so vast it cannot be quantified, like infinite space or infinite love. In everyday speech, 'unlimited' is the safest choice for practical situations (buffets, phone plans, museum passes), while 'limitless' works better for aspirations and 'endless' for things that feel repetitive or continuous.

Etymology

LatinOld EnglishMiddle EnglishEnglish

Formed by adding the negative prefix 'un-' (from Old English) to 'limited', which comes from Latin 'limitatus', the past participle of 'limitare' (to bound or restrict), from 'limes' (a boundary or border). The word has been used in English since the late 1500s, first in legal and philosophical contexts to mean 'not confined by boundaries', and later broadened to everyday use for anything without a cap or restriction.
