mik-RAS-tur
Genus

Literally: small hawk
| Part | Meaning | Language | Note |
|---|---|---|---|
| micr- | small | Greek (micr, -o) | Combining form; connecting vowel dropped before the initial vowel of the following element |
| astur | a hawk | Latin (=astur) | Latin noun used as the terminal element; the initial 'a' of astur merges directly with micr-, making the join seamless |
A compound genus name formed by prefixing the Greek root micr- (small) directly onto the Latin noun astur (hawk). The initial vowel of astur makes a connecting -o- unnecessary. The name is a noun in apposition treated as grammatically feminine (as is conventional for bird genera). The combination is a Greek–Latin hybrid, a common practice in 19th-century taxonomic naming. Micrastur is the genus of the forest-falcons (family Falconidae), small to medium hawks of Neotropical forests — so the name 'small hawk' aptly captures their modest size relative to larger falcons.
Pronunciation
- mik-RAS-tur Three syllables; penult vowel 'a' is short but is followed by two consonants (s + t), so Rule 5 places stress on the penult.
Other readings
An alternative segmentation micr- + a- + stur is not supported; 'stur' has no independent dictionary root. The split micr- | astur is the only well-supported reading.
The name is a deliberate Greek–Latin hybrid: micr- is Greek, astur is Latin. Such hybrids were not uncommon in early 19th-century ornithological nomenclature (the genus was erected by Lesson & Garnot, 1827) and are fully valid under the ICZN Code. The Latin word astur (hawk, goshawk) is also the root of the genus Astur and the family Accipitridae lore; it may ultimately be cognate with Greek aistor (eagle). 'cras-' (Greek: mix, blend) appears inside the string but yields no coherent meaning here and is rejected in favour of the micr- | astur segmentation.
