Pachycephala
pack-ee-SEF-uh-luh
Genus
thick-headed one
Literally: thick head
| Part | Meaning | Language | Note |
|---|---|---|---|
| pachy- | thick | Greek (pach, -y) | combining form pachy- before a consonant |
| -cephal- | the head | Greek (cephal, =a, -o) | stem cephal- |
| -a | nominative singular ending, making the word a feminine noun | Greek (=a) | Latin/NL treatment as feminine genus name |
A single compound Greek word used as a New Latin genus name. The first element pachy- (thick) modifies the head noun cephal- (head); the ending -a gives it feminine gender as a Latin noun in the nominative singular. The name stands alone as a uninomial genus. All other matches from the dictionary (ach-, chy-, cep-, eph-, phal-, hal-, ala-) are artifacts of substring searching and play no etymological role here.
Pronunciation
- pack-ee-SEF-uh-luh Antepenult stress: the penult vowel 'a' in '-al-' is short and followed by only one consonant before the final -a, so stress falls on the antepenult syllable 'ceph' (third from last).
Commonly: pack-ee-SEF-uh-luh (same in common usage)
Other readings
No credible alternative segmentation exists; pachy- + cephal-a is unambiguous.
Pachycephala is a large genus of passerine birds (whistlers and allies; family Pachycephalidae) named for the notably large, rounded heads characteristic of many species. The substrings ach-, chy-, cep-, eph-, phal-, hal-, and ala- are coincidental overlaps with other roots and are not part of the word's etymology.
