Literally: split beak
| Part | Meaning | Language | Note |
|---|---|---|---|
| scissi- | cut, split | Latin (sciss, -i) | combining form with Latin connecting vowel -i- |
| -rostrum | a beak, snout; the prow of a ship | Latin (rostr, =um) | neuter nominative singular; here used as the head noun of the compound |
A Latin compound noun: the adjectival stem scissi- (from scindere, 'to cut/split', perfect passive participial stem sciss-) modifies the head noun rostrum ('beak'). The whole word is neuter (as all -um nouns are), functioning as a single Latin noun in apposition. The name refers to the strongly grooved or notched bill of Scissirostrum dubium, the Finch-billed Myna of Sulawesi.
Pronunciation
- sis-ih-ROS-trum Four syllables: scis-si-ros-trum. The penult vowel 'o' is followed by two consonants (s+t), satisfying penult stress rule 5 (short penult vowel followed by two consonants). Initial sc: 'sc' before 'i' renders the 'c' as 's' (c before i = s); the whole cluster 'sc' → 'ss' sound. Final -um: vowel in final syllable is short 'u'.
Other readings
One could theoretically read sciss-i-rostr-um with -i- as a pure connecting vowel, but the meaning and segmentation are the same either way.
The genus contains a single species, Scissirostrum dubium (Finch-billed Myna), named for its distinctively ridged, almost split-looking bill. All other dictionary hits (ciss-, ostr-, ost-, strum-, etc.) are positional coincidences and do not contribute to the actual etymology. Initial 'Sc' before 'i': by the consonant rule c before i = 's', so 'Sc' is pronounced simply 'ss' (one 's' sound).
