Genus

The great flier — an apt name for the swallow-tailed hummingbird, the largest and most powerful hummingbird in its range

Literally: The well-flying one; the one that flies well

PartMeaningLanguageNote
eu- Good, well Greek (eu) Standard Greek intensifying/qualifying prefix
-petomen- Winged, flying; from the verb pétomai (to fly); petomenos is its present-participle stem meaning 'the one flying' Greek (petin, -o) Dictionary lists the related combining form petin, -o = 'winged, flying' from the same root; the participial stem petomen- (πετόμενος) is not listed as its own entry but is directly derived from the same Greek root
-a Feminine nominative singular ending Standard termination for a Latin-treated feminine genus name

Pure Greek compound. The prefix eu- ('well, good') modifies the present-participle noun stem petomen- ('flying one', from pétomai, to fly), giving a compound noun meaning 'the one that flies well.' The word is treated as a feminine Latin noun and stands alone as a genus name with no species epithet to agree with here.

Pronunciation

  • yoo-peh-TOH-meh-nuh Penult vowel e is followed by only a single consonant (n) with no diphthong or double consonant, so it is light; antepenult vowel o is followed by single consonant m and then two vowels e+a (first being e), making the antepenult long — stress falls on the antepenult (to).

Other readings

eu- + petas/petasma (anything spread out) + -omena: 'the one with well-spread [wings]' — less likely given the clear participial form of petomen-

The participial stem petomen- (Greek πετόμενος, 'flying, the one that flies') is not listed as its own dictionary entry; the dictionary does contain the closely related form petin, -o (Greek, 'winged, flying') from the same root pétomai, confirming the etymology with high confidence. Eupetomena is a monotypic genus established for the swallow-tailed hummingbird (Eupetomena macroura); the name reflects the bird's exceptional speed and flight ability.
