Literally: tody-beak
| Part | Meaning | Language | Note |
|---|---|---|---|
| Todi- | a small bird, a tody | Latin (tod, -i, =us) | combining form todi-, from todus; genitive-style linking form before the head noun |
| -rostrum | a beak, snout; the prow of a ship | Latin (rostr, =um) | neuter noun, nominative singular; functions as the head of the compound |
A Latin compound noun. 'Todi-' is the combining (genitive-like) stem of todus (a small bird, a tody), modifying the head noun rostrum (beak), which sets the grammatical gender of the genus as neuter. The whole name means 'tody-beak', alluding to the broad, flat bill characteristic of these birds (tody-tyrants, family Tyrannidae/Rhynchocyclidae).
Pronunciation
- toh-dee-ROS-trum Penult rule 5: the penult vowel 'o' is short but is followed by two consonants (str), so the penult 'ros' is stressed.
The genus Todirostrum was established by Lesson (1828) for small flycatcher-like birds whose wide, flat bills resemble those of the todies (genus Todus). Several species have since been reclassified, but the name remains valid for the core group. All other dictionary matches (strum, ostr, odi, dir, etc.) are spurious overlaps; the clean two-part split todi- + -rostrum accounts for all eleven letters without remainder and matches the biological context perfectly.
