Erythrotriorchis
eh-RITH-roh-try-OR-kis
Genus (bird of prey, family Accipitridae)
the red hawk; a red-plumaged raptor named after the classical Greek bird name triorchis ("three-testicled")
Literally: red three-testicled (one) — red triorchis
| Part | Meaning | Language | Note |
|---|---|---|---|
| erythro- | red | Greek (erythr, -o) | combining form erythro-, connecting the first element to the rest |
| tri- | three | Greek (tri) | Greek numeral prefix; both Greek τρι- and Latin tri share this form |
| -orchis | testicle; also a plant named for the shape of its roots (orchid) | Greek (orchi, -d, -do, =s) | Here used as the standalone form orchis, the second element of the classical compound τριόρχης (triorchis), Aristotle's name for a buzzard believed to possess three testes; functions as the head noun of the genus name |
The name is a single Greek compound noun used as a Latin-treated genus name (neuter or feminine in form, but treated as a proper noun in apposition). It is built from erythro- (red, combining form) + triorchis, itself the classical Greek word τριόρχης meaning 'three-testicled,' which Aristotle used in Historia Animalium (Book IX) as the name of a specific hawk or buzzard. The compound thus means 'the red triorchis,' modifying the inherited bird-name with a colour prefix. The connecting vowel -o- is the standard Greek combining vowel absorbed into erythro-; tri- attaches directly to -orchis with no additional connector, exactly as in the classical Greek source word.
Pronunciation
- eh-RITH-roh-try-OR-kis Six syllables: e | ryth | ro | tri | or | chis. The penult 'or' has the vowel o closed by the coda consonant r (making it a heavy syllable), so stress falls on the penult by rule 5 (penult vowel followed by two consonants, r + ch). 'ch' is pronounced as hard k throughout. The 'i' of 'tri' is long (open syllable, classical prefix), giving the 'try' sound.
Other readings
A minority reading might try to parse 'trio-' as the Latin word trio (a plough-ox, also used for the stars of the Plough/Ursa Major), giving 'red ox-orchis,' but this is not supported by the zoological context. The correct parsing is erythro- + tri- + orchis, reproducing the ancient Greek compound τριόρχης.
The key to this name is recognising triorchis as a single inherited classical word (Greek τριόρχης, triorkhēs), used by Aristotle for a hawk or buzzard (Historia Animalium 620a) and explained by ancient authors as referring to a bird thought to have three testes. It is not a novel coinage by the genus author but a deliberate reference to the classical raptor name. The dictionary entry for orchi gives 'the testicle; a plant named from the shape of its roots,' confirming the root. The numeral tri is confirmed as 'three' (Greek/Latin). Erythr, -o is confirmed as 'red' (Greek). Erythrotriorchis is a small genus of Australasian goshawks; the best-known species is E. radiatus, the Red Goshawk of Australia, whose common name directly echoes the erythro- prefix. No roots were missing from the dictionary for this name.
