Podilymbus
poh-dil-IM-bus
Genus
The foot-diver — a grebe defined by its remarkable lobed feet
Literally: Foot-diver
| Part | Meaning | Language | Note |
|---|---|---|---|
| Podi- | A foot | Greek (podi, =um) | Stem of pous/podos; -i- functions as a connecting vowel into the following element |
| -lymbus | A diver; a diving bird | Greek (colymb, -i, -o) | From Greek kolumbos / Latin colymbus; Lesson dropped the initial co- to form a compact compound, leaving -lymbus as the terminal element |
| -us | Nominative singular masculine ending | Latin | Standard Latinized genus termination; grammatical gender masculine |
Lesson coined this genus name in 1831 by fusing podi- (Greek 'foot') with the back half of the existing bird-genus name Colymbus (Greek/Latin 'diver'), dropping the co-. The result is a self-standing compound noun treated as masculine Latin in the nominative singular. No specific epithet is being analyzed here; the name stands alone as a genus. The lobed, laterally placed feet of grebes are the anatomical feature being honoured.
Pronunciation
- poh-dil-IM-bus Penult rule 5: the penult vowel y (sounded as short i) is followed by two consonants -mb-, so the penult receives stress
Commonly: Ornithologists universally say poh-dil-IM-bus; rules and common usage agree.
Other readings
A secondary reading splits the word as pod- + ily- + -mbus, where ily- (Greek) means 'mud', yielding 'mud-footed diver'. This is almost certainly a false etymology and not Lesson's intent, but the image is curiously apt for a grebe wading in muddy shallows.
The initial co- of colymbus was deliberately truncated by Lesson to form the compound; the dictionary entry colymb-, -i, -o confirms the root. The segment -lymbus is therefore not independently listed in the dictionary but is directly derived from it. Podilymbus is the genus of the Pied-billed Grebe and its extinct relatives (family Podicipedidae).
