Tachornis
tack-OR-nis
Genus
the swift (fast) bird
Literally: swift bird
| Part | Meaning | Language | Note |
|---|---|---|---|
| tach- | swift, fast | Greek (tach, -in, -y) | Base form; joins directly to a root beginning with a vowel, so no separate connecting vowel is needed |
| ornis | a bird | Greek (orni, =s, -th, -tho) | Standalone form (=s); the initial 'o' of ornis immediately follows tach-, doubling as the natural juncture vowel |
A Greek compound noun in the nominative singular. The first element tach- (swift) functions as an adjectival modifier of ornis (bird), a pattern common in Greek bird-genus names (cf. Tachymarptis, Tachybaptus). The name is a single compound used as a genus name, treated as Latin feminine in accordance with ornis being grammatically feminine in Greek.
Pronunciation
- tack-OR-nis Penult stress rule 5: the penult vowel 'o' (in -chor-) is short but followed by two consonants (r + n), so the penult is stressed.
Other readings
tacho- + ornis: if the 'o' is read as the combining form of tach, -o (speed), the meaning shifts slightly to 'speed-bird' rather than 'swift-bird', but the translation is functionally identical.
Tachornis is a real genus of palm-swifts (family Apodidae), making the meaning 'swift bird' both etymologically and biologically apt. The digraph 'ch' is pronounced as hard 'k' before 'o' following classical scientific-name rules. The 'o' at the join is the initial vowel of ornis, not a separate connecting vowel; when tach- precedes a vowel-initial root, no extra -o- is inserted.
