| Part | Meaning | Language | Note |
|---|---|---|---|
| Oedi- | a swelling, tumor | Greek (oed, -e, =ema, -o) | stem oedo-/oedi-; here the combining form uses -i- as the connecting vowel before the following consonant cluster |
| -i- | connecting vowel | Greek -i- variant of the usual -o- connector, used here before -stoma | |
| -stoma | a mouth | Greek (stom, =a, -ato, -o) | used here in its standalone form -stoma, i.e. stom + final -a; the standard terminal form in compound genus names for 'mouth' |
A Greek compound noun used as a genus name (neuter, treated as Latin neuter singular). The first element oedi- (swelling) modifies the head noun -stoma (mouth), yielding a descriptive compound: 'swollen/puffy mouth.' The name describes the characteristic inflated-looking bill of these small Papuan passerines (family Melanocharitidae, the berrypeckers and longbills). No specific epithet is present; the user supplied only the genus name.
Pronunciation
- ee-DIS-toh-muh Four syllables: Oe-dis-to-ma. Penult 'to' has a short vowel followed by only one consonant (m), so stress falls on the ANTEPENULT 'dis'. Opening diphthong oe = long e (ee). Final -a = unstressed 'uh'.
Other readings
A minority reading might try to parse oed-i- as oed (swelling) + ist-o (web/tissue, Greek ist-) + -ma (noun suffix), but that is far less coherent semantically and the -i- is most simply a connecting vowel.
Oedistoma is a small genus of longbill birds endemic to New Guinea (family Melanocharitidae). The name alludes to the swollen or puffy appearance of the base of the bill. The connecting vowel -i- instead of the more common Greek -o- is unusual but attested in classical Greek compounds; it does not change the meaning. All roots are confirmed in the dictionary.
