The name that is transliterated as «Eutychus» in English means «fortunate,» «happy,» «well off.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines «watching,» «sleeping,» and «falling.» (Eutychus was a boy who, while watching Paul preach, fell asleep and fell out of a window — see Acts 20:9). (Source: Missão Kophós )
