rob-SOH-nee-us
Genus
A genus named in honour of ornithologist Peter Robson
Literally: [The one] of Robson; Robson's [bird]
| Part | Meaning | Language | Note |
|---|---|---|---|
| Robson | Surname of the person honoured; ornithologist Peter Robson | English proper noun | Indeclinable proper-name stem; the tool matched rob (Latin: strong, oak) and son (Latin: sound) but those are false coincidental segmentations — the name is a unitary patronym, not a Latin compound |
| -i- | Connecting/euphonic vowel inserted between the stem's final consonant and the Latin suffix | Standard New Latin convention easing pronunciation | |
| -us | Nominative singular masculine ending | Latin | Places the name in the Latin second declension, masculine gender |
The surname Robson is taken as an indeclinable stem. The suffix -ius (= connecting -i- + nominative -us) attaches it to the Latin second declension, yielding a masculine genus noun in the nominative singular: Robsonius. As a genus name it stands alone; any species epithet added to it must agree in gender (masculine), or be a genitive or noun in apposition.
Pronunciation
- rob-SOH-nee-us Antepenult stressed because the penult vowel (i in 'ni') is short and not followed by two consonants; the antepenult vowel (o in 'so') is long by the rule: o + single consonant n + two following vowels i·u whose first is i.
Commonly: rob-SON-ee-us (penult stress heard in everyday English speech, by analogy with the surname Robson)
Other readings
A purely coincidental Latin segmentation rob- (robur, 'strength/oak') + son- (sonus, 'sound') + -ius + -us = 'strong-sounding' is theoretically possible but almost certainly not intended; patronymic formation is the standard and overwhelmingly likely interpretation.
The suffix -ius is not a standalone entry in the dictionary but is the universally recognised Latin suffix used to Latinize surnames into second-declension genus names (confidence: high). The dictionary returned rob (Latin robur, 'strong; oak') and son (Latin sonus, 'sound') as matches, but these are false positives arising from the patronymic stem; they are not the intended etymology. Robsonius is a genus of Philippine ground-babblers (family Locustellidae), erected to honour Peter Robson, ornithologist.
