と

In our second lesson about と, we will look at the common translation of 'with' that is associated with this particle. と shows that there is a relationship between (A) and (B), regardless of if that relationship is translated as 'and', or 'with'.

In either case, the nouns that are marked with と are usually all performing some mutual action (that mutual action may simply be existing).

When と is used as 'with', it means that both/all people or objects are equally involved in the action. However, に highlights that one person is the target (destination) of an action, so will result in something sounding a lot more one sided.

Here we can see that both people are talking when と is used. It is a mutual conversation. When に is used, however, the person marked by に is being talked 'to', and is usually not actively participating in the conversation.
