What does earwax mean?
Earwax is the yellowish, waxy substance produced by glands lining the outer ear canal of humans and many other mammals. Medically known as cerumen, it plays a protective role: it lubricates the delicate skin of the ear canal, traps dust and small particles, and carries dead skin cells and debris outward. In ordinary speech the word appears most often in discussions of hygiene or hearing — people talk of excess earwax, a buildup of earwax, or having earwax removed by a doctor. It is a neutral, uncountable noun used comfortably in both casual and clinical contexts, though medical professionals tend to prefer cerumen. The word is transparently formed from ear plus wax, and its meaning has been stable since it entered English in early modern times. Despite its slightly unglamorous associations, earwax names something genuinely useful: without this modest secretion, the ear would be far more vulnerable to dryness, infection, and injury.

"The doctor removed a buildup of earwax that had been causing her muffled hearing."
"Excessive earwax can lead to temporary hearing loss and a sensation of fullness in the ear."
"He winced as the nurse gently scooped a stubborn plug of earwax from his ear canal."
Earwax is self-cleaning: your ears push old wax out on their own, so doctors say you should never stick a cotton swab in — it just packs the wax deeper.

Etymology of earwax
Earwax is a straightforward English compound of ear and wax, first recorded around the early seventeenth century. The word simply names what it describes — a waxy substance associated with the ear — and has cognates in other Germanic languages, such as German Ohrenschmalz, which literally means ear fat or grease. Its Latin-derived medical synonym, cerumen (from Latin cera, meaning wax), was adopted later for clinical use.
How earwax is actually used
The word is neutral in register and used in both everyday conversation and medical contexts; the clinical term is cerumen. It is an uncountable mass noun with no standard plural form.
