Actinodura
ak-ti-no-DU-ra
Genus
the rayed tail (a bird with conspicuously streaked or barred tail feathers)
Literally: ray-tail
| Part | Meaning | Language | Note |
|---|---|---|---|
| actino- | a ray, beam | Greek (acti, -no, =s) | combining form of aktis/aktinos; the -o- is already the combining-form vowel |
| -d- | euphonic connector inserted by the author between the -o of actino- and -ura | a linking 'd' occasionally added by 19th-century naturalists to prevent hiatus; not a separate morpheme | |
| -ura | the tail | Greek (ur, =a, -o) | terminal form of ur-/oura; here the stem's initial vowel elides against the preceding -o-d- to give -ura |
A compound noun formed from Greek actino- (ray) plus Greek -ura (tail), with an authorial euphonic -d- bridging them. The genus name stands alone as a nominative singular noun treated as feminine (ending -a). The construction is wholly Greek. The name alludes to the strongly barred or streaked tail pattern of these birds (the barwings, family Leiothrichidae), coined by Hodgson in 1838.
Pronunciation
- ak-ti-no-DU-ra Penult rule 4: the penult vowel is 'u' followed by a single consonant (r); most such penults are stressed.
Commonly: ak-TI-no-du-ra (antepenult stress is heard in common speech, treating -ura as a light ending)
Other readings
actino- (ray) + dura (Latin, hard) = 'hard ray' — a Greek–Latin hybrid that is grammatically possible but biologically less apt and etymologically inelegant.
The euphonic -d- between actino- and -ura has no dictionary entry of its own; it is an authorial insertion well documented in 19th-century ornithological names (cf. Melanodryus, Lepidodura). The Latin reading actino- + dura (hard) cannot be excluded on purely formal grounds but is not supported by the morphology of the other Actinodura species names or by Hodgson's annotations. 'ura' (tail) is confirmed in the dictionary as ur, =a, -o (Greek).
