[General] run across vs run into

[daemon99]

1) I ran across this expression when I was reading a novel last night.
2) I ran into this expression when I was reading a novel last night.

Can someone please tell me which of the above sentences sounds natural?

2) I ran into this expression when I was reading a novel last night.

Can someone please tell me which of the above sentences sounds natural?

I would say "I came across this expression..."

:up: 'Run across', like 'bump into' (when it's used metaphorically, and doesn't involve a low-speed crash ;-)), is used of people: 'I ran across an old friend at the conference'.
