Pityriasis
pit-ih-RY-uh-sis
Medical / dermatological term; also used as a genus name (Aves: Pityriasis gymnocephala, the Bornean bristlehead)
a bran-like scaly condition
Literally: presence (or formation) of bran
| Part | Meaning | Language | Note |
|---|---|---|---|
| pityr- | bran, refuse | Greek (pityr, -o, =um) | stem pityr-; the bare stem is used before the vowel-initial suffix -iasis, so no connecting vowel is needed |
| -iasis | treatment, cure; formation of, presence of | Greek | Greek suffix used in medicine to denote a pathological condition; the initial -i- of the suffix immediately follows the stem |
The word is a pure Greek compound: the bare noun stem pityr- (bran) + the medical suffix -iasis (condition / presence of). It functions as a Latin feminine singular noun in scientific nomenclature (as is standard for disease names and many genus names). When used as a bird genus the name alludes to the bird's scaly, bran-like head plumage.
Pronunciation
- pit-ih-RY-uh-sis Five syllables: pit-y-ri-a-sis. Penult vowel 'a' is short and followed by only one consonant (s), so penult stress is not triggered. Antepenult vowel 'i' (in 'ri') is immediately followed by another vowel ('a'), making it long; a long antepenult takes the stress.

Other readings
A very superficial alternative split might try pityo- (pine/fir) + r + iasis, but that is phonologically forced and semantically weak; the pityr- (bran) reading is the unanimous medical and etymological consensus.
Both roots (pityr- and -iasis) are confirmed in the dictionary. The 'y' in Pityriasis represents Greek upsilon (υ), conventionally rendered as a short 'ih' sound in English medical pronunciation. As a bird genus, Pityriasis (Lesson, 1839) contains a single species, P. gymnocephala (the Bornean bristlehead); the name refers to the crimson, scaly-looking bare skin on the bird's head.
