Usage Note

Common Mistakes

Grammar Patterns

be + chronic

Usage Note

This sense is informal and mainly used in British English, not American English. It describes the quality of an experience or thing — it does NOT carry the 'long-lasting' meaning of sense 1. Typically appears in predicative position (after be): 'The film was chronic,' not 'a chronic film.'

Common Mistakes

This weather is so chronic!' (American listener may misunderstand).
This weather is so bad!
The informal sense of chronic is mainly British; in the US it is almost always interpreted as 'long-lasting'.

Synonym discussion

Sense: adjective/1

All five words describe situations that last over time, but they differ in tone and scope. Chronic carries a strong negative tone and is most at home in medical contexts (chronic pain, chronic illness), though it also applies to social problems (chronic unemployment). Persistent is more neutral — it can describe annoying habits (persistent cough) or admirable effort (persistent work). Long-term is the most factual and neutral; it is used for plans, goals, and relationships (long-term investment, long-term friendship). Ongoing focuses on something still in progress (ongoing investigation), without judging its length. Recurring means something happens repeatedly rather than continuously (recurring dream, recurring issue). For example, a chronic cough suggests it never goes away, while a recurring cough comes back every few weeks.

Etymology

GreekLatinFrenchEnglish

Chronic comes from the Greek word 'chronos' (χρόνος), meaning 'time.' It entered English through Latin 'chronicus' and French 'chronique,' originally used in medicine to describe diseases that last a long time — as opposed to 'acute' diseases. The informal British meaning 'very bad' developed in the 20th century, perhaps as a shortened form of 'chronic bad' or from the idea that something bad that lasts a long time becomes extremely unpleasant.
