What does deaf mean?
Deaf is an adjective describing someone who has little or no ability to hear, whether the loss is partial or total. It applies to people born without hearing as well as those who lose hearing later in life through illness, injury, or age. Beyond its literal medical sense, deaf carries important cultural weight: many members of the signing community capitalize the term as "Deaf" to signal identity and belonging rather than disability, and organizations increasingly prefer respectful phrasing such as "hard of hearing" for milder losses. Figuratively, deaf describes anyone stubbornly ignoring advice or appeals — a warning that falls on deaf ears goes unheard by choice, not necessity. The word appears in familiar idioms like "turn a deaf ear" and intensifying phrases such as "stone deaf." With roots stretching back to Old English, it is among the oldest words in the language, making it both practically essential and historically rich.
Lacking wholly or partially the sense or power of hearing.
"The school offers specialized support for children who are deaf or hard of hearing."
Refusing or failing to listen; heedless or indifferent (figurative).
"Management remained deaf to employees' concerns about working conditions."
The phrase "fall on deaf ears" has been around since at least the 15th century — yet the word "deaf" itself traces back over a thousand years to Old English, making it one of the oldest words in the language.

Etymology of deaf
The word deaf descends from Old English dēaf, which itself comes from Proto-Germanic *daubaz, meaning unable to hear. It is a true native Germanic word, with close cognates including German taub and Dutch doof. Unlike many English words borrowed from Latin or French, deaf has been part of the language continuously for over a millennium, retaining remarkably stable form and meaning throughout.

How deaf is actually used
Many people prefer terms like "hard of hearing" for partial loss, while "deaf" is used both as a neutral descriptor and as a proud identity marker within the Deaf community, where capitalization ("Deaf") signals cultural membership rather than mere audiological status. The older phrase "deaf and dumb" is now considered offensive and should be avoided.
