Somateria
soh-mat-EER-ee-uh
Genus
the woolly-bodied one — referring to the extraordinarily thick, insulating down feathers (eiderdown) of eider ducks
Literally: woolly body
| Part | Meaning | Language | Note |
|---|---|---|---|
| somat- | a body | Greek (=soma, -t, -to) | stem of σῶμα (soma); the oblique/combining stem is somat- |
| -eri- | wool | Greek (erio) | from Greek ἔριον (erion); the combining form erio- contracts to -eri- before the final vowel |
| -a | feminine nominative singular ending | New Latin | standard Latinised genus-name ending; grammatical gender feminine |
A single compound word built entirely from Greek roots and given a Latinate feminine -a ending, as required for a genus name under the ICZN. The stem somat- (body) is modified by the combining form eri(o)- (wool), yielding the sense 'woolly body'. No epithet is being analyzed here; Somateria is a monomial genus name. The genus was erected by Leach (1819) for the eider ducks, whose famous down feathers inspired the name.
Pronunciation
- soh-mat-EER-ee-uh Penult vowel 'i' is short and followed by only a single vowel (not two consonants), so penult stress is excluded. Antepenult 'e' in '-er-' is followed by a single consonant 'r' and then two vowels 'i, a' (the first being 'i'), making it long by the antepenult long-vowel rule → stress falls on the antepenult, and the 'e' is pronounced as a long 'ee'.
Other readings
A minority reading could segment the second element as eri- alone (meaning 'wool; very much; early') rather than erio-, but both forms share the same Greek root ἔριον and yield the same meaning. No other credible segmentation exists.
The Greek word for wool appears in the dictionary both as 'eri' and as 'erio'; the combining form erio- is the more specific wool-entry and is the one used here. Both point to Greek ἔριον. Somateria contains the eider ducks (e.g. S. mollissima, the Common Eider), whose underplumage — harvested as eiderdown — directly motivated the name 'woolly body'. The -a ending is a standard Latinisation, not the Greek alpha-privative prefix a- (meaning 'not/without'), which would be a different initial segment.
