| cephal- | The head | Greek (cephal, =a, -o) | Stem cephal-, combining form cephalo-; here the -o- of cephalo- is elided before the final vowel |

Macrocephalon is a New Latin genus name formed from two Greek combining forms. Macro- (large) modifies cephal- (head), and the whole compound is given the neuter Greek/Latin nominative ending -on, making it a neuter noun in apposition (genus name stands alone, no species epithet supplied). The name refers to the conspicuous raised casque or knob on the head of the Maleo bird (Macrocephalon maleo), the sole species in this genus of megapodes from Sulawesi.
Pronunciation
- mak-roh-SEF-uh-lon Antepenult stressed: the penult vowel (-a-) is short and is followed by only a single consonant (l), so the stress shifts back to the antepenult syllable (-ceph-). The 'c' in 'ceph' is softened to 's' because it precedes 'e'.
Other readings
No credible alternative segmentation exists; macr-o-cephal-on is unambiguous.
The ending -on is not listed as a separate dictionary entry; it is the standard Greek/New Latin neuter nominative singular suffix, well established in biological nomenclature (e.g. Ichthyosaur-on, Mammal-on analogues), and is treated here from general knowledge (in_dictionary: false). Macrocephalon is a monotypic genus: its only species is Macrocephalon maleo (Schlegel & Müller, 1845), the Maleo, a megapode bird of Sulawesi, Indonesia. The large bony casque on the bird's forehead inspired the name.
