What are euphemisms in 'Antigone'?

It is particularly in Antigone's last scene that euphemisms are found in "Antigone" by Sophocles (495 B.C.E. - 405 B.C.E.).

Specifically, euphemisms are round about ways of discussing delicate or heart wrenching topics. For example, Theban Princess Antigone offers euphemisms for death. For example, she speaks of Hades giving sleep to mortals. She then talks of setting forth on her last trip, which is a euphemism for death.
