Sylviorthorhynchus
sil-vee-or-thoh-RINK-us
Genus
the straight-beaked [bird] of the forest
Literally: forest straight-beak
| Part | Meaning | Language | Note |
|---|---|---|---|
| sylvi- | woods, forest | Latin (sylv, =a, -at, -estr, -i) | Combining form sylvi-; the -i- here serves both as the Latin combining vowel and as part of the root stem |
| ortho- | straight, upright | Greek (orth, -o) | Greek combining form ortho-; note that the name mixes Latin (sylvi-) and Greek (ortho-, -rhynchus), making it a hybrid compound |
| -rhynchus | a snout, beak | Greek (rhynch, -o, =us) | Terminal form -rhynchus; Latinized masculine nominative singular ending -us, used as the head noun of the compound; the initial rh- reflects Greek ῥύγχος (rhunkhos) |
The name is a single compound genus name treated as a Latin masculine noun. It is built from three elements: the Latin combining form sylvi- (forest) + the Greek combining form ortho- (straight) + the Greek terminal noun-form -rhynchus (beak), yielding a noun meaning 'the straight-beaked one of the forest.' The compound follows the common 19th-century practice of combining a Latin modifier with a Greek head noun. Sylviorthorhynchus is the monotypic genus of the Des Murs's Wiretail (S. desmursii), a furnariid passerine of Patagonian shrublands; the name refers to its notably straight, fine bill.
Pronunciation
- sil-vee-or-thoh-RINK-us Six syllables: syl-vi-or-tho-rhyn-chus. The penult 'rhyn' has a short vowel (y = short i) followed by two consonants (n + ch = k), satisfying Rule 5 (short penult vowel followed by two consonants), so the penult receives stress.
Other readings
The first element could theoretically be parsed as the genitive/combining form of the genus name Sylvia (a wren-warbler), i.e., 'Sylvia-like straight-beak,' but the direct derivation from Latin sylva/sylva (woods) is more parsimonious and etymologically standard.
The name is an intentional Latin–Greek hybrid, combining Latin sylvi- with Greek ortho- and -rhynchus. Such hybrids were common and accepted in 19th-century zoological nomenclature. The 'y' in 'Sylvi-' is pronounced as a short 'i' (as in 'sit') in English scientific pronunciation, giving 'sil-' not 'syl-' (as in 'style'). 'ch' in -rhynchus is always a hard 'k', never 'ch' as in 'church'. The initial 'rh-' in -rhynchus is simply pronounced 'r'; the h is silent in English rendering of the Greek ῥ (rho with rough breathing). Sylviorthorhynchus desmursii (Des Murs's Wiretail) is the only species in the genus, native to Chile and Argentina.
