Genus
the cuckoo
Literally: a cuckoo
| Part | Meaning | Language | Note |
|---|---|---|---|
| cucul- | a cuckoo | Latin (cucul, -i, =us) | 2nd-declension masculine noun stem; the word is also onomatopoeic, echoing the bird's 'cu-cu' call |
| -us | nominative masculine singular ending, 2nd declension | Latin | marks grammatical gender and case; used unchanged as the genus name |
Cuculus is a straightforward Latin masculine noun of the 2nd declension (stem cucul-, nominative cuculus). Used as a genus name it stands alone in the nominative, with no epithet here. The -us ending is the standard nominative singular for masculine 2nd-declension nouns. The word itself is likely onomatopoeic in origin, mimicking the cuckoo's 'cu-cu' call, and is the direct ancestor of the English word 'cuckoo'.
Pronunciation
- KYOO-kyoo-lus Three syllables: an-te-pen-ult rule applies. The penult vowel (u in the second cu-) is short and followed by only one consonant (l), so it does not attract stress. Stress therefore falls on the antepenult (first cu-). That antepenult u is followed by a single consonant (c/k), making it long (long-u rule), pronounced 'yoo'.
Commonly: KOO-koo-lus (many English speakers reduce both long-u syllables to 'oo', by analogy with the English word 'cuckoo')
Other readings
A superficial reading could split cu- + -culus and interpret -culus as the Latin diminutive suffix ('little'), yielding 'little cu-'. This is almost certainly a false split: the dictionary records cuculus as a single, indivisible stem meaning 'a cuckoo', and the -ulus coincidence is purely accidental.
Cuculus is the type genus of the family Cuculidae (cuckoos), established by Linnaeus in 1758. The genus name is the unaltered classical Latin word cuculus, itself almost certainly onomatopoeic. The diminutive suffix -culus/-ulus is present in the same dictionary and superficially matches the ending of this word, but the dictionary entry treats cuculus as a whole, independent lexeme, not a derived diminutive. No roots are missing or ambiguous; confidence is high throughout.
