lat-er-AL-us
Genus
The flank-rail (a small rail bird with distinctive lateral markings)
Literally: side-rail; the rail of the flanks
| Part | Meaning | Language | Note |
|---|---|---|---|
| later- | the side, flank | Latin (later, -al, -o) | Stem of latus, lateris (the side); appears here as later-, the genitive stem |
| -allus | rail (the bird); used as a compound suffix meaning 'a kind of rail' | New Latin (Rallus) | New Latin genus name Rallus (rails, family Rallidae), modified to -allus to form a Latinized compound; Rallus itself derives from Old French rasle (rail bird) and is not in the roots dictionary |
Laterallus is a New Latin masculine noun coined by G. R. Gray (1855) by fusing the Latin stem later- (side, flank) with a clipped and Latinized form of Rallus (-allus), yielding a compound noun meaning 'a small or lateral Rallus'. It functions as the sole genus name (no species epithet is given), standing as a Latin noun of the second declension, masculine, nominative singular. The construction is a standard 19th-century ornithological compound: a descriptive modifier + the parent-genus name serving as the head.
Pronunciation
- lat-er-AL-us Penult rule 5: the penult vowel 'a' (in '-al-') is short but is followed by two consonants (ll), so the penult is stressed.
Other readings
lat- (broad, wide, from lat, -i) + er- (connecting) + -allus: 'broad little rail' — less likely, as lat- would normally appear as lati- before a following consonant
later- (brick, from lateri-) + -allus: 'brick-rail' — phonetically possible but semantically implausible
'Rallus' (the parent rail genus) is not found in the roots dictionary; its inclusion here is based on general ornithological and etymological knowledge (confidence: high). The segment -allus is not a standard Latin diminutive suffix (-ulus would be the norm); its form is best explained as Rallus with its initial R- replaced by the junction with later-, a practice common in 19th-century genus coinages. 'Laterallus' likely alludes to the strongly barred or rufous flanks that characterize many species in the genus, consistent with the Latin later- = 'side/flank'.
