плющя

Heterogenous:

• Durative-iterative of onomatopoeia плю́сък (pljúsǎk, “splash, slap”) +‎ -я (-ja), from Proto-Slavic *pľuskъ. Parallel to плю́кам (pljúkam), плю́гам (pljúgam), плю́сам (pljúsam), пля́скам (pljáskam), пле́щя (pléštja) from similar onomatopoeias.
• Causative of плю́ска (pljúska, “swelling, bulging”) +‎ -я (-ja), from Proto-Slavic *pľuska < Proto-Balto-Slavic *pljauskāˀ (whence Lithuanian pliaũskė (“billet, chump”)).
• Possibly from a sk-inchoative derivative of Proto-Balto-Slavic *pjáuˀtei (“to chop, to hack”) with expressive sense, akin to Lithuanian pjáuti (“to cut”), Latvian pļaut (“to reap, to mow”).
