The word has Latin roots: 'inter' means 'between' and 'agieren' means 'to act'. So 'interagieren' (to interact) describes an action that takes place between two or more parties and is based on reciprocity.

to react
'reagieren' and 'interagieren' both have to do with response and influence. 'reagieren' usually describes a response to something: a person, a body, or a substance changes because something happened beforehand. 'interagieren', on the other hand, emphasizes contact in both directions. People speak with each other and influence each other; things or substances can also influence each other. Learners may confuse the words because reactions often also happen during an interaction. The difference is: 'reagieren' is often a response to a trigger, while 'interagieren' is a mutual interplay.
