Aix
AKES
Genus
a waterbird (the word also meant 'goat' in Greek, but the genus name alludes to its waterfowl sense)
Literally: a goat; a waterfowl
| Part | Meaning | Language | Note |
|---|---|---|---|
| Aix | A goat; a waterfowl | Greek (=aix) | Greek nominative singular used whole as the genus name. The waterfowl sense motivated Kaup (1829) when he erected this genus for perching ducks. Grammatical gender is feminine, following the ICZN convention for bird genera and the feminine gender of the Greek source word. |
Aix is a uninomial genus name — a single Greek word borrowed intact into New Latin nomenclature, treated as a feminine noun. There are no combining forms, connecting vowels, or suffixes. Species names placed in this genus (e.g. Aix galericulata, Aix sponsa) must agree with its feminine gender.
Pronunciation
- AKES Monosyllable — the entire word is the one stressed syllable. The diphthong ai = long a ('ay'); final x = 'ks'.
Other readings
Some authors have noted the primary meaning of Greek aix is 'goat' (cf. Capella, Capricorn); Kaup almost certainly intended the secondary sense 'waterfowl', which ancient Greek authors used for a diving bird, but the dual meaning is an amusing coincidence.
Dictionary entry =aix (Greek): 'A goat; a waterfowl.' Both meanings are attested in ancient Greek; the waterfowl sense is the one relevant to the duck genus Aix Kaup, 1829 (family Anatidae), which contains the Wood Duck (Aix sponsa) and the Mandarin Duck (Aix galericulata). As a monosyllable, stress placement is trivial — there is only one syllable to stress. The cross-reference entry for 'ai' in the dictionary simply redirects to ae/e/oe (a diphthong note), confirming that Aix should be read as a single unit, not split into a prefix + root.
