sucus

• succus

From Proto-Italic *soukos, from Proto-Indo-European *sewg-, *sewk- (“juice; to suck”), itself possibly borrowed from Proto-Uralic *śuwe (“mouth”). Cognate with sūgō, Welsh sugno (“to suck”), sugnedydd (“pump”), Latvian sùkt (“to suck”), Proto-Slavic *sъsàti (“to suck”), and English suck. Apparently unrelated to Proto-Slavic *sokъ of the same meaning.
