haemophiliac
C2 / Low-frequencyTechnical / Medical / Formal
Definition
Meaning
A person who suffers from haemophilia, a medical condition where the blood does not clot properly.
The term refers specifically to the individual affected by the inherited genetic disorder. It is also used attributively to describe things related to or characteristic of the condition (e.g., haemophiliac patient).
Linguistics
Semantic Notes
The word is a countable noun (person). It is a clinical, diagnostic label. Care should be taken to use person-first language (e.g., 'a person with haemophilia') in contexts where identity-first language may be seen as insensitive.
Dialectal Variation
British vs American Usage
Differences
The primary difference is in spelling. British English predominantly uses 'haemophiliac' (with 'ae'), while American English uses 'hemophiliac' (with just 'e').
Connotations
Identical in meaning and clinical connotation. The UK spelling reflects a stronger adherence to the word's Greek etymology (haima, 'blood').
Frequency
The word is more frequent in its American English spelling ('hemophiliac') in global medical literature due to the predominance of US publications. Within the UK medical community, 'haemophiliac' is standard.

Common Pitfalls
Translation Traps (for Russian speakers)

- Avoid confusing with similar-sounding terms like 'haemorrhage' (кровотечение).
Common Mistakes
- Misspelling: 'hemophiliac' (US) vs 'haemophiliac' (UK).
- Confusing with 'haemorrhage' (a major bleed).
- Using the term in a non-person sense (e.g., 'a haemophiliac disease' is incorrect; it's 'haemophilia').

FAQ
Frequently Asked Questions
In formal medical contexts, it is standard. In general conversation, person-first language ('a person with haemophilia') is often preferred as it emphasises the individual over the condition.
Yes, the pronunciation is identical: /ˌhiː.məˈfɪl.i.æk/. The difference is purely in spelling.
Yes, though it is far rarer. Haemophilia is an X-linked recessive disorder, meaning it predominantly affects males, but females can be carriers and, in rare cases, manifest the condition if they inherit affected X chromosomes from both parents.
Haemophilia A is caused by a deficiency in clotting factor VIII, while Haemophilia B (Christmas disease) is caused by a deficiency in factor IX. Both result in similar symptoms, and a person with either condition is correctly termed a haemophiliac.
