T.S. Eliot used the term:
\[
\text{Objective Correlative}.
\]
It means a set of objects, situations, images, or events that can evoke a particular emotion in the reader.
According to Eliot, emotion should not be stated directly.
Instead, the poet should present suitable external objects or events.
These objects or events create the required emotion in the reader's mind.
So, objective correlative is not direct emotional explanation.
It is an indirect artistic method of producing emotion.
Therefore, Eliot's objective correlative means:
\[
\text{Set of images/events that creates the emotions}.
\]
