Literally: spur-tailed / pointed-tailed
| Part | Meaning | Language | Note |
|---|---|---|---|
| centro- | the center; a point, spur | Greek (centr, -i, -o, =um) | combining form centro-; here the sense 'a point, spur' applies, referring to the stiff, spike-like tail feathers |
| -cercus | the tail | Greek (cerc, -o, =us) | standalone form -cercus (nominative singular, treated as masculine in genus names); the Greek κέρκος (kerkos) |
A compound noun used as a genus name, treated as Latin masculine nominative singular in -us. The first element centro- (combining form of Greek kéntron, 'point, spur') modifies the head noun -cercus (Greek kérkos, 'tail'). Together they form a single descriptive noun: 'spur-tailed.' This is a noun in apposition (or a descriptive compound), a common pattern in bird genera coined in the 19th century. Centrocercus is the genus of the sage-grouse (family Phasianidae); the name alludes to the long, stiff, spike-like central tail feathers of the males.
Pronunciation
- sen-troh-SER-kus Penult rule 5: the penult vowel (e in -cer-) is short but is followed by two consonants (r + c), so the penult is stressed.
Other readings
centr- could theoretically be read as 'center' (as in 'center-tailed'), but 'point / spur' fits the bird's morphology far better and is supported by the same dictionary entry.
The dictionary entry for centr gives two senses: 'the center' and 'a point, spur' (from Greek kéntron, originally 'a goad or prick'). The biological context — the pointed, spine-like tail feathers of the sage-grouse — strongly favors the meaning 'point / spur.' The consonant cluster -rc- in the penult (cen-tro-cer-cus) triggers penult stress by Rule 5 (short vowel followed by two consonants). 'c' before 'e' is pronounced 's' (English/Anglicized convention), giving 'sen-' and 'ser-'; 'c' before 'u' in the final syllable is 'k', giving '-kus'.
