What does interact mean?
To interact means to act, respond, or communicate with another person, object, group, or system. The word usually suggests a two-way exchange rather than a one-sided action: people interact through conversation, cooperation, shared activities, or physical engagement, while technology and natural processes interact through signals, forces, or other mechanisms. In everyday use, “interact with” often describes participation in a social or working relationship, as in interacting with colleagues or online services. The term also has a technical application in computing, referring to a user operating software or an interface. Although “interact” is related to the more familiar “interaction,” the verb is particularly useful for describing the actions involved in reciprocal engagement. It can sound somewhat formal in some contexts, but it is broadly accepted in British and American English.

Where does interact come from?
The word was formed in English from the Latin prefix inter-, meaning “between” or “among,” and the Latin verb agere, meaning “to do” or “to act.” Its development reflects the idea of acting in relation to something else. The same Latin root underlies English words such as action, active, agent, and agenda.
