Interpretation

DEFINITION :  Interpretation is understanding the meaning of a theme.


EXAMPLE :

O Captain! My Captain!

O CAPTAIN! my Captain! our fearful trip is done;
The ship has weather'd every rack, the prize we sought is won;
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring:
But O heart! heart! heart!
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.


O Captain! my Captain! rise up and hear the bells;
Rise up--for you the flag is flung--for you the bugle trills; 10
For you bouquets and ribbon'd wreaths--for you the shores a-crowding;
For you they call, the swaying mass, their eager faces turning;
Here Captain! dear father!
This arm beneath your head;
It is some dream that on the deck,
You've fallen cold and dead.


My Captain does not answer, his lips are pale and still;
My father does not feel my arm, he has no pulse nor will;
The ship is anchor'd safe and sound, its voyage closed and done;
From fearful trip, the victor ship, comes in with object won; 20
Exult, O shores, and ring, O bells!
But I, with mournful tread,
Walk the deck my Captain lies,
Fallen cold and dead. 

In the line "Here Captain! dear father!", the word father actually means Lincoln and because a father is the leader of a family and Lincoln is the president of the US.

SIGNIFICANCE :  Interpreting a poem is important because just reading a
                                poem doesn't helps you at all. If you interpret the poem in
                                 a right way, you might get the theme and understand the
                                poem better.
