End, termination, ending, terminus are comparable when opposed to beginning or starting point and meaning the point or line beyond which a thing does not or cannot go (as in time or space or magnitude).
End is not only the ordinary but also the most inclusive of these terms, and it may be used of almost any final limit and in such varied applications as time or movement or action or magnitude or range of possibility.
Termination and ending apply especially to the end in time or, less often, in space of something that is brought to a close typically as having a set term or bounds or predetermined limits or as being complete, finished, or futile.
Terminus applies to the end (often in clear opposition to starting point ) to which a person or a thing moves or progresses. The term usually suggests spatial relations and often indicates a definite point or place.
