Usage Note

Often used with verbs describing waiting, duration, or difficulty (wait, take, last, feel like, go on). This sense is hyperbolic — it exaggerates the length of time rather than stating a literal fact.

We waited for quite a while at the red light.
Use this sense only when the wait genuinely felt very long to the speaker.

The movie was so boring that it felt like it would last forever.
Add 'felt like' or 'seemed' to show it is the speaker's perception, not a fact.

Synonyms
  • constantly

    less emotional; can be neutral or positive, not limited to annoyance

  • continually

Grammar Patterns

be forever + verb-ing

Usage Note

Almost always used with progressive verb forms (is forever doing, was forever losing). Without the progressive aspect, the meaning shifts to sense 1 (for all time). Carries a clear tone of mild annoyance or complaint.

Common Mistakes

She forever arrives late to meetings.
She is forever arriving late to meetings.
Without the progressive form, readers will interpret 'forever' as 'for all time' (sense 1).
I am forever grateful for your help.' (intended as 'very often')
I am forever grateful for your help.' is actually sense 1 (permanent state). If you mean 'very often,' use 'I am constantly grateful' or restructure.

Synonym discussion

Sense: adverb/1

All four words describe something that lasts or continues, but they differ in register and scope. 'Forever' (the most common, A2-level word) is emotional and personal — people promise to love someone forever or hope good memories last forever. 'Permanently' is more factual and neutral; you might say the museum is permanently closed or the damage is permanent. 'Eternally' carries poetic or spiritual weight, often referring to the divine or to unchanging truths ('eternally grateful'). 'For good' is informal and suggests a decisive, final end: 'She left for good' means she is never coming back. Use 'forever' for heartfelt personal statements, 'permanently' for official or formal contexts, 'eternally' for dramatic or religious tones, and 'for good' for casual statements about final decisions.

Etymology

Old EnglishMiddle EnglishEnglish

From Middle English 'for ever,' a phrase meaning 'for all time.' The two-word form 'for ever' was standard through the 16th century, and gradually the single-word 'forever' became common in the 17th and 18th centuries. The adverbial phrase was formed from 'for' (meaning 'throughout' or 'during') + 'ever' (meaning 'always' or 'at all times'). The noun use (e.g., 'it took forever') emerged in informal 19th-century English, and the adjective use (e.g., 'forever home') developed in the late 20th century.
