Stercorarius is a Latin adjective of the -arius type formed on the oblique stem stercor- of stercus ('dung'). Used as a substantive (adjective standing alone as a noun), it denotes one who pertains to or is characterised by dung. Brisson (1760) coined it as a genus name for skuas and jaegers in reference to their kleptoparasitic habit of harassing other seabirds until they regurgitate food, the stolen meal being likened to filth. As a single-word genus there is no epithet relationship to resolve. The word is masculine, as expected for a genus name ending in -us.
Pronunciation
- ster-cor-AIR-ee-us Antepenult stress: the penult vowel (-i-) is short and followed by only one consonant, so penult stress is not triggered. The antepenult vowel (a in -ar-) is followed by a single consonant (r) and then two vowels (i, u), the first being i, making the antepenult vowel long by rule — stress therefore falls on the antepenult syllable -AR-.
Commonly: Informally often heard as ster-KOR-uh-ree-us, with stress shifted to the penult by analogy with words like Aquarius; the antepenult form is preferred in formal nomenclature.
Other readings
No alternative segmentation is compelling. A split at sterc-or-arius (treating -or- as a separate suffix) is theoretically possible but yields no better meaning; stercor- as the unified oblique stem is the standard Latin analysis.
The suffix -arius is not present as a standalone entry in the dictionary but is one of the most productive Latin adjectival suffixes and is identified here from general knowledge (high confidence). stercus / stercor- is confirmed in the dictionary as Latin for excrement, dung, manure. The genus Stercorarius (Brisson, 1760) gives its name to the family Stercorariidae (skuas and jaegers). The same Latin root yields the English medical adjective stercoral (relating to faeces).
