peakab
kh កាព្យ kab "sounding similar" + ពាក្យ peak "word".
ពាក្យកាព្យ peakab indicates the homophony in កំណាព្យ kamnap, poetic style. Khmer poetics (and language) often recourse to homonymy, words that have different meanings but are pronounced the same way.
Traditional Khmer versification follows the stanza form called វគ្គនៃកំណាព្យ wek nei kamnap, from វគ្គ wek "session", "group of syllables". For melodious music, the Khmer has an all-together word, ពិរោះ piroah.
