Grammar Patterns

hence + clause

hence + noun phrase

Usage Note

In formal writing, 'hence' is often used to begin a sentence that states a logical conclusion from the previous sentence. 'Hence' can be followed by a full clause or directly by a noun phrase (without a verb).

Common Mistakes

I was tired, hence I went to bed early.
I was tired; hence, I went to bed early.
'Hence' should connect two clauses with a semicolon (or start a new sentence) rather than follow a comma.

  • months hence
  • years hence
  • a decade hence
Synonyms
Antonyms

Grammar Patterns

[number] + [time unit] + hence

Usage Note

This sense is almost always used with a specific number or quantifier before a time word (e.g., 'a week hence,' 'five years hence'). It is characteristic of formal, legal, and academic writing; in everyday English, people prefer 'from now' (e.g., 'two years from now').

Common Mistakes

Hence two years, I will graduate.
I will graduate two years hence.
The time expression must come before 'hence,' not after.

3. away from this location — now found almost exclusively in historical, literary,

3.adverbC2
Definition

away from this location — now found almost exclusively in historical, literary, or highly formal language.

Example

The messenger departed hence at midnight, carrying urgent news for the king.

archaic/literary use: depart + hence

'Get thee hence,' the old story reads, 'and never set foot in this village again.'

biblical/literary formula: get thee hence

Synonyms
  • away

    modern equivalent; far more common

  • from here

    everyday alternative for this sense

Antonyms

Grammar Patterns

verb + hence

Usage Note

This sense is now archaic in everyday English. It survives in fixed literary expressions ('get thee hence,' 'go hence'), historical fiction, and translations of classical or biblical texts. Modern readers will encounter it far more often in reading than in speech or writing.

Common Mistakes

❌ 'I am moving hence tomorrow.' (in a casual conversation) — This sounds unnatural in modern English. Use 'away from here' or 'from here' instead.

Idioms

Used to say that something will happen a certain amount of time in the future.

The project deadline is three weeks hence.

Will you still remember this moment a year hence?

Synonym discussion

Sense: adverb/1

'Therefore,' 'thus,' 'consequently,' 'accordingly,' and 'hence' all indicate a logical result, but they differ in tone and typical contexts. 'Therefore' is the most neutral and widely used — it works in speech and writing across all registers. 'Thus' carries a slightly literary feel and is common in academic prose, often introducing a method or conclusion ('The sample was heated; thus, the metal expanded'). 'Consequently' emphasises the cause-effect relationship and is preferred in formal reports to stress that one event directly produced another. 'Accordingly' is more common in legal and administrative language, where it signals that an action follows a rule or precedent. 'Hence' sits between 'thus' and 'consequently' in formality — it can introduce either a full clause or a noun phrase, making it useful for concise explanatory sentences. For example: 'The evidence was inconclusive; hence, the case was dismissed.' In this context, 'therefore' would also work but sound less formal, while 'consequently' would add weight to the causal link.

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

'Hence' comes from Old English 'heonan' meaning 'from this place,' which developed from a Proto-Germanic root *hin- (meaning 'this one' or 'that one') combined with an ablative suffix indicating movement away. By the Middle English period, it had already acquired its temporal meaning ('from this time') and, later, its logical meaning ('as a result of this'). The three senses — spatial, temporal, and logical — all share the core idea of moving away from a starting point, whether a place, a moment in time, or a preceding statement.
