passerby vs bystander

[blingbang]

Can I use both? Or... they require an appropriate context to be used?

 

[Cypherpunk]

As always, please provide context. These words do not mean the same thing, but they might both work in some situations, so we need to see the context to answer.

Okay

Context

"We better stop and ask a bystander for some directions."

I put it together I hope it's correct.

Both of these words are clearly defined in the Dictionary at the top of the page; therefore, no, you wouldn’t normally use “bystander” in your example.
