incus
C2/TechnicalScientific/Medical/Technical
Definition
Meaning
The middle of the three small bones (ossicles) in the middle ear, shaped like an anvil.
A central element or structure in a system that resembles an anvil in shape or function; in meteorology, the anvil-shaped top of a mature thundercloud.
Linguistics
Semantic Notes
The primary sense is anatomical. The Latin root 'incus' means 'anvil,' and this shape is the defining characteristic. In meteorology, it refers to the flattened, anvil-like cloud top.

Examples
By CEFR Level
- The doctor said the three tiny bones in the ear have special names.
- Some big storm clouds have a flat, anvil-shaped top.
- Sound vibrations pass from the malleus to the incus and then to the stapes in the middle ear.
- The cumulonimbus cloud's distinctive anvil, called the incus, signals a mature thunderstorm.
- Otosclerosis can fixate the ossicles, preventing the incus from transmitting vibrations effectively.
- The meteorologist noted the well-developed incus spreading downwind, indicating a severe storm with a stable upper layer.
Learning
Memory Aids
Mnemonic
Imagine the word 'in-cuss' (as in 'to curse inside'). You might curse inside if you damage the tiny 'incus' bone in your ear.
Conceptual Metaphor
TOOL FOR TRANSFER (The incus is a tool/anvil that transfers force/sound vibrations).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with Russian 'наковальня' (anvil tool) – 'incus' is specifically a bone or cloud structure. In anatomy, the direct translation is 'наковальня' (the bone), but the context is critical.
Common Mistakes
- Mispronouncing as /ɪnˈkjuːs/ or /ˈɪnkʊs/.
- Using it as a general term for 'anvil' outside scientific contexts.
- Confusing it with 'incense'.

FAQ
Frequently Asked Questions
No, it is a highly specialized term used almost exclusively in anatomy/medicine and meteorology.
The standard plural is 'incudes' (/ɪŋˈkjuː.diːz/ or /ˈɪŋ.kjəˌdiːz/), though 'incuses' is sometimes seen.
No. While it comes from the Latin word for anvil, in modern English, 'incus' is not used for the tool. Use 'anvil' instead.
Remember the order: Malleus (hammer) hits the Incus (anvil), which sits on the Stapes (stirrup). The incus is the middle one, shaped like an anvil.
