Slaveni means Glorious in Slavic.
Slovo is letter.
Skla-Veni is combination of two different groupations Scoloti and Veneti. Scoloti are eastern Scythians or R1a haplogroups and Veneti are of I2 haplogroup or ancestral European male.
Insulting and probably demeaning intentions stood after naming a originaly þeow or þræl as slave so that it sounds like Slavs.
Slave, "to enslave," from slave (n.). The meaning "work like a slave" is first recorded 1719.
Later on Grose's dictionary (1785) has under Negroe "A black-a-moor; figuratively used for a slave," without regard to race.
More common Old English words for slave were þeow (related to þeowian "to serve") and þræl (see thrall).
In late 13c., "person who is the chattel or property of another," from Old French esclave (13c.), from Medieval Latin Sclavus "slave" (source also of Italian schiavo, French esclave, Spanish esclavo), originally "Slav" (see Slav); so used in this secondary sense because of the many Slavs sold into slavery by conquering peoples.
Sclaveni exist much longer, first left is Sklavinia.
