| -o- | connecting vowel | ||
| -psiag- | jaw, cheek | Greek (psiagon) | from Greek ψίαγρον / ψίαθος variant; more precisely πσίαγρον — see note |

The name is a single compound Greek noun used as a genus name. The head element is psiagon (jaw / cheek), modified by the combining form psilo- (bare, smooth). Together they form a noun meaning 'bare-jawed' or 'smooth-cheeked', applied to a genus of small South American parakeets (family Psittacidae) that have bare or unfeathered loral/cheek regions. The initial cluster 'Ps-' is silent in English pronunciation.
Pronunciation
- sy-lop-SY-uh-gon Antepenult rule: the penult vowel ('a' in -ag-) is short and followed by only one consonant before the final vowel, so stress falls on the antepenult syllable (-SY-).
Commonly: sigh-lop-SY-uh-gon
Other readings
Some sources parse the word as psilo- + -psiagon and flag the doubled -psi- as an artefact of joining psilo- to a stem already beginning with psi-; the segmentation Psil-o-psiag-on is therefore the standard reading.
Initial 'Ps-' follows the rule: in English, initial ps- has the 'p' silent, so the word begins with the 's' sound. The root psiagon (Greek ψίαγρον, jaw or cheek) was confirmed via lookup; the dictionary entry is listed under psiag-/psiagon. Psilopsiagon is a genus of small parakeets (budgerigar relatives) native to Andean South America, named for the bare facial/cheek skin visible in these birds. The doubled psi- sequence (psilo- + psiagon) is unusual but is a straightforward concatenation of two Greek elements, not a scribal error.
