  • truth

    broader, more abstract — 'truth' can refer to a general principle or moral correctness, while 'fact' usually points to a specific verifiable item

  • reality

    focuses on the actual state of things, often contrasting with how things appear or are imagined

  • certainty

    emphasises the absence of doubt rather than the evidence itself

反義詞
  • fiction

    something invented or imagined

  • lie

    a deliberate false statement

  • opinion

    a personal belief that may or may not be true

文法句型

the fact that + clause

用法筆記

Can be used as a countable noun ('several facts') or as an uncountable noun ('separate fact from fiction'). The uncountable form treats truth as a general quality rather than individual items of information.

It is a fact that the Earth is round.
💡after 'the fact' or 'a fact', use a 'that'-clause, not a 'what'-clause.
That is a factually information.
That is factual information.
💡'factual' is the adjective form; 'factually' is an adverb.

as a matter of fact

同義詞
  • actually

    similar function; 'actually' is more common in everyday spoken English, while 'in fact' is slightly more formal

  • indeed

    more formal and emphatic; 'indeed' often reinforces a point rather than correcting it

文法句型

in fact

as a matter of fact

the fact is (that)

用法筆記

This sense only appears in fixed phrases — 'in fact', 'as a matter of fact', and 'the fact is (that)'. The word 'fact' does not stand alone with this meaning. Unlike sense 1, 'a fact' or 'the fact' without one of these phrases will not convey emphasis or correction.

常見錯誤

In fact, I don't like it actually.
In fact, I don't like it at all.
💡using both 'in fact' and 'actually' in the same clause is redundant.

例句

pattern: cannot ignore the fact that…

同義詞
  • the reality that

    similar meaning but slightly more formal and often used for broader situations

  • the circumstance that

    more formal; emphasises the surrounding conditions rather than the truth itself

文法句型

the fact that + clause

用法筆記

Commonly followed by a 'that'-clause describing the situation. The phrase 'the fact that…' functions as a noun phrase and can act as the subject, object, or complement of a sentence. Distinguish from sense 2: sense 3 'the fact that' introduces a known situation as a topic, while sense 2 'the fact is' makes an emphatic statement.

常見錯誤

Due to the fact the flight was delayed, we missed our connection.
Due to the fact that the flight was delayed, we missed our connection.
💡the 'that' is required after 'the fact' in standard English.

例句

the fact of the matter is (that)…

accept the fact that…

同義詞
  • reality

    broader; 'reality' can refer to any actual situation, while 'fact' in this sense emphasises unavoidability

  • given

    more formal; a 'given' is something assumed to be true without question

文法句型

the fact of the matter is

accept the fact that

a fact of life

用法筆記

Often appears in the fixed phrases 'the fact of the matter is that…' and 'a fact of life'. The focus is on inevitability — the speaker or writer is signalling resignation or acceptance rather than presenting new information.

常見錯誤

I need to face the fact.' (without further context)
I need to face the fact that I am not good enough.
💡'face the fact' needs a 'that'-clause specifying what the fact is.

the facts of the case

collocation: relevant facts

同義詞

    broader — 'details' can include unimportant or unverified information; 'facts' implies the information has been checked

  • particulars

    more formal; often used in legal or administrative contexts

  • data

    refers to raw information, often numerical; 'facts' are interpreted and verified data points

文法句型

the facts about / of / on

用法筆記

Almost always used in the plural. Common in journalism, law, police work, and official reports. 'The facts' in this sense implies a complete or sufficient set of details, not just one isolated piece.

常見錯誤

💡in this sense, 'facts' is almost always plural.
