[Vocabulary] Picking the correct preposition for the verb "to look up"

[euncu]

Hello ,

I know that we look something up in a dictionary and also know that we look something up on the internet. So which one is the right one to pick if I look something up in/on an online dictionary?

Thanks for your help in advance.

I see no reason as to why it would change.

I would use "in" for an on-line dictionary.

So you say it should be "in", am I right?

I would use "in" for an online dictionary as well. I think it's just because the phrase "to look something up in a dictionary" is so well-established that it would be hard to change anyway, but there is no reason to in this case. You are still looking in/within/inside the contents of a dictionary and its listings, even if that dictionary is held on the internet.
