What does, "God speed" or is it "God's speed" mean?

May the good lord watch over you for a safe and successful journey.

Webster says that godspeed comes from Middle English “god speid”, meaning “may God make you prosper”.

@SadieMartinPaul so would it be correct to say it to a dead person on an online obituary type thread? In other words, John Doe died a month ago and was a priest. People are on the thread saying nice things about him and someone wishes him God’s speed. Is that proper?

@Aster If people are saying “godspeed” to someone who’s recently departed, they must be wishing him a quick and sure voyage to heaven.

@thorninmud – The Greek word “prosper” is euodoo (yoo-od-o’-o) which means “to have a successful journey through life.”

@SadieMartinPaul I suspected that was the case.

It is “godspeed”, and I agree with those who answered above.

Actually, I think the phrase has been consistently misrepresented. I believe the correct expression is:

God’s peed, which can be a reference to weather, or just shitty days in general.

There’s a bomb on the holy bus?
