Selasphorus
seh-LAS-for-us
Genus
The flame-bearer — evoking the brilliant, iridescent plumage of these hummingbirds, which flashes like fire in sunlight
Literally: Radiance-bearer; carrier of shining light
| Part | Meaning | Language | Note |
|---|---|---|---|
| selas- | Bright, shining; a flash or blaze of light | Greek (sela, -sm, -t) | Stem-final -s retained as the junction consonant; Greek σέλας |
| -phor- | Carry, bear; movement | Greek (phor, -a, -e, -i, -o) | Greek -φόρος, 'bearer'; the 'carry/bear' entry is the relevant sense here |
| -us | Nominative singular ending, masculine gender | Latin | Standard Latin termination applied to Latinized Greek genus names |
Selasphorus is a masculine Latin nominative singular noun formed from two Greek stems joined directly (no connecting vowel needed, as selas- ends in a consonant and -phor- begins with one). The suffix -us Latinizes the Greek compound for use as a genus name. Species epithets in this genus must be masculine when adjectival (e.g. -us/-er), or may stand as a genitive or noun in apposition regardless of gender.
Pronunciation
- seh-LAS-for-us Antepenult stress: the penult vowel (o in -pho-) is short and followed by only one consonant (r), so no penult-stress rule is triggered; stress defaults to the antepenult syllable (-las-).
Other readings
The segment -phor- could theoretically be read as the other dictionary entry meaning 'a thief; a kind of bee', but 'light-bearing' is overwhelmingly supported by context and ornithological usage.
Genus established by William Swainson in 1832 for a group of North American hummingbirds (family Trochilidae). The Greek noun σέλας (selas) specifically denotes a bright flash or blaze of light, making the name a direct reference to the fiery iridescent gorgets characteristic of these birds. No roots were missing from the dictionary; all segments confirmed by tool lookups.
