collocation: external injury

Common collocations
  • external wall
  • external surface
  • external injury
  • external appearance
  • external factor
  • external force
  • external pressure
  • external environment
  • external source
Synonyms
  • outer

    slightly less formal; 'outer layer' is a common collocation while 'external layer' sounds technical

  • outside

    everyday alternative; 'outside wall' is more natural in conversation than 'external wall'

Antonyms
  • internal

    direct opposite; 'internal' refers to the inside of a system, object, or organisation

Grammar Patterns

external + noun

be external to + noun phrase

Usage Note

Attributive only — you can say 'the external wall' but NOT 'the wall is external' in everyday use. The pattern 'external to + noun phrase' is more formal and common in academic or business writing.

Common Mistakes

The external of the building looks old.
The outside of the building looks old.
'external' is an adjective, not a noun, when referring to physical surfaces. Use 'outside' or 'exterior' as the noun.

2.adjectiveB2
Definition

relating to or involving other countries, especially in matters of trade, politics, finance, or international relations.

Example

collocation: external investment

Indra studied external trade policies between the EU and Southeast Asia.

collocation: external trade

Common collocations
  • external trade
  • external policy
  • external affairs
  • external relations
  • external investment
  • external debt
  • external market
  • external threat
  • external border
Synonyms
  • foreign

    more common in everyday use; 'foreign policy' is interchangeable with 'external policy' in formal writing

  • international

    broader scope; includes multilateral and global contexts rather than strictly bilateral cross-border matters

Antonyms
  • domestic

    the opposite in political and economic contexts; 'domestic trade' vs 'external trade'

Grammar Patterns

external + noun (trade, policy, affairs, investment)

Usage Note

Commonly paired with nouns like 'trade', 'policy', 'affairs', 'relations', 'investment', 'debt'. In this sense 'external' contrasts with 'domestic' (inside the country), not with 'internal'.

Common Mistakes

The company has many external partners in the same city.
The company has many international partners in the same city.
'external' for 'foreign' implies cross-border relationships, not just outside one organisation.

3.adjectiveC1
Definition

based on outward appearance only, having little connection with what is real, important, or essential about a person, situation, or thing.

Example

Ada felt their praise was purely external, not a genuine recognition of her work.

adverb: purely external

The logo changes were merely external and did nothing to fix the brand's real problems.

adverb: merely external

Common collocations
  • purely external
  • merely external
  • strictly external
  • external appearance only
  • external show
  • external formality
Synonyms
  • superficial

    more direct and common in everyday speech; 'superficial' carries a clearer negative judgement

  • outward

    neutral register; 'outward calm' describes appearance without implying deception or emptiness

Antonyms
  • essential

    what is truly important or fundamental rather than surface-level

  • intrinsic

    belonging naturally to something rather than being merely apparent

Grammar Patterns

purely/merely/strictly external

external + noun (appearance, show, formality)

Usage Note

Often modified by 'purely', 'merely', 'only', or 'strictly' to emphasise the contrast with inner reality. Can be used predicatively (e.g. 'the harmony was only external'), unlike the OUTSIDE sense.

Common Mistakes

His kindness was external.
His kindness was only a superficial show.' or 'His kindness was purely external.
Without a modifier like 'purely' or 'merely', the sentence sounds odd because this sense almost always needs emphasis on the outward-only nature.

Synonym discussion

Sense: adjective/1

All four words refer to the side or area that is not inside, but they differ in scope and register. 'External' is the most formal and broadest term — it can refer to physical surfaces ('external wall'), origins ('external factor'), or international matters ('external trade'). 'Outer' is narrower and almost always physical: it describes the layer farthest from the centre ('outer layer', 'outer space') and does NOT extend to abstract or international senses. 'Outside' is the everyday, conversational word for the physical side of something ('outside of the box', 'the outside wall') and is also the natural noun choice ('the outside of the building'). 'Exterior' sits between 'outside' and 'external' in formality, typically referring to the visible surface of a building, vehicle, or object ('the car's exterior'). In everyday conversation, use 'outside' or 'outer' for physical contexts; reserve 'external' for formal, technical, or abstract contexts.

Etymology

LatinFrenchEnglish

The word 'external' comes from the Latin 'externus', meaning 'outward' or 'outside', which itself is formed from 'ex-' (meaning 'out'). The suffix '-al' was added in English to turn it into an adjective, following the pattern of other Latin-derived words. The noun sense emerged later in the 17th century, originally used in philosophical writing to describe things existing outside the human mind.
