false rib
C1Technical (Anatomy, Medicine), occasionally literary or metaphorical.
Definition
Meaning
A rib that is not directly attached to the sternum (breastbone) via its own costal cartilage, specifically ribs 8–10, which attach to the cartilage of the rib above.
In anatomy, one of the lower ribs that do not have a direct anterior connection to the sternum, distinguishing them from 'true ribs'. In broader, metaphorical use, can refer to something that appears to be a fundamental support but is actually secondary, indirect, or not integral.
Linguistics
Semantic Notes
A strictly anatomical term with a precise definition. Its metaphorical use is rare and typically found in specialized prose (e.g., philosophical or architectural metaphors about structure and support). It is a hyponym of 'rib'.
Dialectal Variation
British vs American Usage
Differences
No difference in anatomical definition or terminology. Potential minor spelling differences in surrounding text (e.g., 'cartilage' vs. 'cartilage' is same).
Connotations
Identical technical connotations. Non-technical metaphorical use is equally rare in both varieties.
Frequency
Extremely low frequency in general discourse, used exclusively in anatomical/medical contexts. Frequency is identical in both UK and US English within those fields.

Usage
Context Usage
Academic
Essential in medical, biological, and anatomical texts, courses, and research. Used with precise definition.
Everyday
Virtually never used in everyday conversation unless discussing a specific injury or anatomy lesson.
Technical
The primary context. Used in clinical reports, surgical planning, anatomy textbooks, and physiotherapy.
Examples
By Part of Speech
adjective
British English
- The false-rib cartilages form the costal margin.
- He suffered a false-rib injury in the match.
American English
- The false-rib cartilage was examined in the lab.
- A false-rib fracture can be less painful than a true rib fracture.
Examples
By CEFR Level
- The lower ribs in your chest are called false ribs.
- A blow to the side can damage a false rib.
- In the dissection, we identified the false ribs by tracing their cartilage to the seventh costal cartilage rather than the sternum.
- The poet described the colonnade as 'the building's false ribs, elegant but not bearing the true weight of history'.
Learning
Memory Aids
Mnemonic
"False" friends don't connect directly; **false ribs** don't connect directly to the breastbone. Think: "The false eight are a bit late to attach to the sternum's plate."
Conceptual Metaphor
STRUCTURE IS A SKELETON / SUPPORT IS RIBBING. A 'false rib' can metaphorically represent indirect support, a non-essential structural element, or something that appears foundational but is not.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'ложное ребро' in a non-anatomical context, as it will sound nonsensical. In anatomy, the correct term is 'ложное ребро'.
- Avoid confusing with 'плавающее ребро' (floating rib), which is a sub-category (ribs 11–12).
Common Mistakes
- Using 'false rib' to refer to the floating ribs (11–12) only. (False ribs are 8–12, with 11–12 being 'floating' *within* the false rib category).
- Capitalising the term (False Rib).
- Using it in a general sense to mean 'broken rib'.

FAQ
Frequently Asked Questions
Not exactly. All floating ribs (ribs 11 and 12) are false ribs, but not all false ribs are floating. False ribs (8–12) attach indirectly. Floating ribs (11–12) are the subset of false ribs that have no anterior attachment at all.
Typically, a human has five pairs of false ribs (ribs 8–10, which attach indirectly, and ribs 11–12, the floating ribs), making 10 individual false ribs in total.
They are called 'false' because they lack a direct, independent cartilaginous connection to the sternum (breastbone), unlike the 'true' ribs (1–7).
Almost never. It is a specialised anatomical term. You might encounter it in a medical context after an injury, in a biology class, or in very rare metaphorical language.
