Irediparra is a compound genus name formed from a contracted patronymic stem (Iredi-, from Iredale) joined by the connecting vowel -i- to the existing ornithological genus name Parra (the jacana genus established by Linnaeus). The whole word is treated as a Latin feminine noun in the nominative singular, as required for a genus name under ICZN. The combination literally means 'the parra (jacana) of Iredale', functioning as a noun in apposition rather than a Latin genitive or adjectival construction. It was coined by Mathews (1911) to accommodate the comb-crested jacana of Australasia.
Pronunciation
- eye-RED-ih-PAR-uh Compound of two elements. The name has five syllables: I-re-di-par-ra. The whole word follows the antepenult rule: the penult is 'par', whose vowel is short and followed by only one consonant before the final -a, so stress would fall on the antepenult 'di'. However, as a transparent compound of Iredi + parra, both halves carry natural stress — Iredi is stressed on its second syllable (RED) and parra on its first (PAR) — giving a double-stress reading that reflects the compound structure and matches ornithological convention.
Commonly: eye-RED-ih-PAR-uh (consistent with ornithological usage)
Other readings
Some sources parse Iredi- as a direct truncation of the surname Iredale with the final syllable -ale dropped and -i added as a connective, rather than as a separate connecting vowel; the result is the same either way.
A minority reading treats the full first element as 'Iredi' (an independent stem) + 'parra' with no connecting vowel, but the -i- is most naturally read as a connective.
'Iredi-' is not in the roots dictionary; it is a contracted patronymic stem from the surname Iredale (Tom Iredale, ornithologist). This is confirmed by general ornithological knowledge (confidence: high). 'Parra' is not listed in the roots dictionary as a separate entry; it is a classical Latin bird name adopted directly into Linnaean ornithology for jacanas. Marked in_dictionary: false but confidence is high. Irediparra gallinacea (the Comb-crested Jacana) is the sole species in this genus, found across New Guinea and Australia. The genus was established by Gregory M. Mathews in 1911.
