Anthracoceros
an-thruh-KOH-seh-ros
Genus
the coal-black horn [bird]
Literally: coal horn
| Part | Meaning | Language | Note |
|---|---|---|---|
| anthrac- | coal, charcoal; a carbuncle | Greek (anthra, -c, =x) | Combining form of anthrax (ἄνθραξ); the stem anthraco- appears before the connecting vowel. Here the 'coal-black' color of the hornbill's casque is the reference. |
| -o- | connecting vowel | Standard Greek linking vowel joining the two roots | |
| -ceros | horn | Greek (cera, -t, -to / =kera, -to) | From Greek keras (κέρας), genitive keratos; the Latinized nominative form -ceros is the conventional terminal element in zoological genus names (cf. Rhinoceros, Monoceros). The dictionary records the root as cera, -t, -to and =kera, -to, both meaning 'horn'; the standalone terminal -ceros is not listed separately but is the nominative singular of the same stem. |
Anthracoceros is a noun in the nominative singular functioning as a genus name and treated as grammatically masculine in Latin. It is a pure compound of two Greek roots: anthrac(o)- (coal) + ceros (horn), joined by the connecting vowel -o-. The compound refers to the conspicuously dark (coal-black) casque — the helmet-like 'horn' on the bill — that characterises hornbirds in this genus (family Bucerotidae, Asian pied hornbills).
Pronunciation
- an-thruh-KOH-seh-ros Five syllables: an | thra | co | ce | ros. Penult 'ce' has a short vowel (e followed by single consonant r) → stress falls on the antepenult 'co'. The antepenult vowel o is short. C before o = k; c before e = s.
Commonly: an-THRAK-oh-see-ros (informal; stress shifted to the second syllable, treating 'anthraco' as a block)
Other readings
An alternative but less likely reading might take anth- (Greek: flower, brilliancy) + -raco- + -ceros, but anthraco- as a single combining form for 'coal/charcoal' is overwhelmingly standard and biologically appropriate.
The terminal element -ceros (Greek keras, κέρας, 'horn') does not appear as a standalone entry in the dictionary under that exact spelling, but the root is fully attested as cera, -t, -to and =kera, -to, both meaning 'horn' (Greek). Confidence is high. Anthracoceros Reichenbach 1849 is the accepted genus of Asian pied hornbills; the name alludes to the coal-black coloring of the casque and upper bill. The connecting vowel -o- belongs to the anthraco- combining form, not to ceros; the split is anthrac-o-ceros, not anthraco-c-eros.
