The term 'INEVITABLE' is an adjective that describes something that cannot be avoided or prevented. It is often used to describe a situation that is certain to happen, regardless of any attempts to stop it. The term 'IMMINENT' is also an adjective that describes something that is about to happen or is likely to occur soon. Both terms are related in that they both refer to something that is unavoidable and certain to happen. INEVITABLE is the more extreme of the two, as it implies that the event is certain to happen, while IMMINENT suggests that it is likely to happen soon.
