eardrum
B2neutral, leaning slightly towards technical/medical in careful usage, but common in general contexts.
Definition
Meaning
The thin membrane inside the ear that vibrates when sound waves strike it; part of the hearing mechanism.
The structure forming the boundary between the outer and middle ear; the tympanic membrane. By extension, it can be used metaphorically to refer to one's hearing or to a sound being unpleasantly loud.
Linguistics
Semantic Notes
Refers strictly to an anatomical part. The term is countable and typically singular in reference to one's own ears ('my eardrum burst'), but can be plural for general cases or when referring to both ears. Not typically used in a possessive sense (e.g., not 'the eardrum's function').

Memory Aids
Mnemonic
Think of an EAR DRUM: your ear has a thin skin like a drum that 'beats' or vibrates when sound hits it.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing from Russian 'барабанная перепонка' as 'drum membrane' or 'drum partition'. Use only 'eardrum' or 'tympanic membrane'.
- The word 'eardrum' is a single, solid noun, not a phrase.
Common Mistakes
- Misspelling as 'ear drum' (should be one word or hyphenated: 'eardrum' or 'ear-drum').
- Using it as an adjective (e.g., 'eardrum pain' is acceptable, but 'eardrum specialist' is less common than 'ear specialist').
