Hirundapus
hih-RUN-da-pus
Genus
The swallow-swift — a bird like a swallow but footless (or nearly so), i.e. a needletail swift
Literally: swallow-footed (without feet like a swallow); the swallow-swift
| Part | Meaning | Language | Note |
|---|---|---|---|
| Hirund- | a swallow | Latin (hirund, -in, =o) | Stem of Latin hirundo (nominative), hirundin- (oblique stem); the -o of hirundo is dropped before the following element |
| a- | without, not | Greek (a) | Greek alpha-privative prefix; also the first element of the established genus name Apus |
| -pus | a foot | Greek (-pus / =pous) | Greek πούς (pous), accusative πόδα, combining form -pus; the element a- + pus together reproduce the genus name Apus (swifts), literally 'without feet', alluding to their vestigial legs |
Hirundapus is a compound genus name (masculine, following the gender of the embedded -apus element). It is formed from the Latin noun stem hirund- (swallow) directly prefixed to the Greek compound a-pus (without foot), which was already established as the genus name Apus for typical swifts. The whole word is thus a blended neo-Latin coinage: Latin hirund- + Greek apus, meaning 'the footless swallow' or equivalently 'the swift that is swallow-like.' The -a- between hirund- and pus is not a connecting vowel but the Greek privative prefix belonging to -apus. It is a hybrid Latin–Greek compound, standard practice in ornithological nomenclature of the 19th century.
Pronunciation
- hih-RUN-da-pus Four syllables: hih-RUN-da-pus. Penult is 'da': short vowel 'a' followed by only one consonant (p), so penult stress rules 2–5 do not apply. Stress falls on the antepenult 'RUN'. The antepenult vowel 'u' is short (followed by two consonants nd, but that governs penult stress, not antepenult quality here).
Other readings
One might parse hirund + -apus as simply 'swallow + Apus (swift genus),' treating -apus as a reference to the genus Apus rather than analyzing a- and pus separately; the biological meaning is the same — these are the needletail swifts, larger relatives of Apus.
The dictionary does not contain a standalone entry for 'apus', but it is clearly resolvable as Greek a- (without) + -pus (foot), both of which are individually in the dictionary. Confidence is high. Hirundapus is a 19th-century genus of needletail swifts (family Apodidae). The name deliberately echoes both Hirundo (the swallow genus, Latin) and Apus (the swift genus, Greek), capturing the bird's swallow-like appearance and swift-like near-footlessness. The compound is a Latin–Greek hybrid, which was accepted without restriction under the nomenclatural codes of the time.
