Reconstruction

The numeral is *pénkʷe in the HCHIEL morphology chapter by Lundquist and Yates, in Ringe, and in Mallory and Adams.[1][2][3] Kroonen and Martirosyan write *pénkʷe and *pénkwe,[4][5] Beekes, de Vaan and Derksen *penkwe or *penkʷe,[6][7][8] and Smoczyński *penku̯e.[9] Byrd's phonology chapter in HCHIEL gives the phonetic form as *peŋkʷe, since the nasal assimilated in place of articulation to a following stop, as in all the old languages.[10]

Morphology

Like the other numerals from 'five' to 'ten', it was not inflected for case, number or gender.[1][11] Clackson cites it as a word with two e-grades, against the idea that each word had a single *e at the place of the accent.[12] Mallory and Adams also set up a derivative *pénkʷti-, in Old Church Slavonic пѧть (pętĭ, “five”), Albanian pesë (“five”) and the Sanskrit word for 'group of five',[11] which de Vaan writes Sanskrit पङ्क्ति (paṅktí).[7] Derksen too thinks that Slavic added the suffix *-ti- to the uninflected numeral.[8] The oldest ordinal was *pn̥kʷtós, with later full-grade *pénkʷtos formed separately in most branches.[11]

Evidence

Mallory and Adams list it among the words with cognates in all the major groups.[13] Italic and Celtic regularly assimilated *p…kʷ to *kʷ…kʷ, which gives Latin quīnque, while Germanic shows an irregular assimilation to *p…p.[11] Kroonen explains the Germanic form by a sporadic change of *kʷ to *p after a resonant in words that begin with a labial.[4] Kroonen also lists Hittite panza- among the cognates.[4]

Competing analyses

Sihler finds the comparison with *ponkʷ-to-, *ponkʷu- 'all, whole', in Latin cūnctus and Hittite panku-, the most persuasive of its kind, 'five' as 'the whole hand', but holds that such etymologies cannot be tested.[14] Mallory and Adams find the semantic step weak and take the Hittite word to come from *bhonĝhu- 'thickness'; they find the comparison with Proto-Uralic 'palm of the hand' too loose to convince.[15] Kloekhorst rejects Polomé's derivation of the Hittite word from *penkʷe because the u-stem cannot reflect a labiovelar.[16] Kroonen thinks the Germanic word for 'fist' probably derived from 'five'.[17]
