What does adenoidal mean?
Adenoidal is an adjective with two closely related uses. In its medical sense, it describes anything pertaining to the adenoids — the pads of lymphatic tissue at the back of the nasal passage — or affected by their enlargement, a condition common in children that can cause mouth-breathing and muffled speech. Far more often, however, the word appears in everyday and critical writing to describe a voice that sounds nasal, pinched, or whining, as though forced through a blocked nose. A singer might be praised or teased for an adenoidal delivery, and a complaining character might be given an adenoidal whine. The term derives from the Greek 'aden', meaning gland, via 'adenoid'. Because it almost always implies an unattractive vocal quality, it tends to carry a mildly negative or humorous connotation, making it a vivid choice for describing distinctive — if not always beloved — ways of speaking.
adjectiveRelating to or affected by enlarged adenoids, especially in a way that affects the voice. More broadly, describing a voice that sounds nasal, pinched, or whining.
- Of a voice: sounding nasal, pinched, or whining, as if produced through a blocked nose.
- Medically: relating to the adenoids, or affected by enlarged adenoids.
"He spoke in a thin, adenoidal voice that seemed to come entirely from his nose."
"The singer's adenoidal delivery became his signature sound, instantly recognizable on every track."
"The doctor noted the child's persistent mouth-breathing and adenoidal speech as signs of enlarged adenoids."
The word for a stuffy-nosed voice literally comes from Greek 'aden' meaning 'gland' — so when someone sounds adenoidal, you're technically calling their voice glandular.

Etymology of adenoidal
Adenoidal derives from 'adenoid', a nineteenth-century anatomical term formed from the Greek 'aden' (gland) plus '-oid' (resembling), originally describing gland-like tissue. When the lymphatic tissue at the back of the nose was identified and named the adenoids, 'adenoidal' arose as its adjective form. The word shares its Greek root with other medical terms such as 'adenoma' and 'adenitis'. Its figurative extension to describe nasal-sounding voices followed naturally from the effect enlarged adenoids have on speech.
