Meaning & History
This name can be a hellenized form of Blasius (see Blaise), but it can also be a genuine Greek name in its own right. In that case, it is derived from the Greek noun βλαστός (blastos) meaning "young shoot, bud, sprout", which itself is ultimately derived from the Greek verb βλαστέω (blasteo) meaning "to sprout". Also compare the Greek noun βλάστη (blaste) meaning "growth". Finally, the name Blasios is an old name - Vlasios is the modern form. It should be noted, though, that despite being different from each other, both Blasios and Vlasios are technically spelled the same in the Greek script (namely, as Βλάσιος). This is explained by the fact that the first letter of the name (the beta) was a 'b' in ancient Greek, but it is a 'v' in modern Greek.
