Poetry and Poem

To differentiate poetry and poem we should first understand what is the difference between prose and poetry..

The difference between prose and poem:

'' Poem is a work which is made up of highly rhythmic and lyrical words."

It is used to express the imagination of a poet in an extraordinary form. When poet/poetess writes poem, his or her feeling is not like a common person. They think different, they can see different and express their observation and views differently. That makes poem. 

i.e., 

Simple sentence: 

The sun and moon looks like they are revolving around the earth.

Poem :

 The sun and moon revolving around the Earth;

              As if they suggest the circle of death and Birth. (Self made)

The difference between  Poem and Poetry:

- Poem is a form in which both forms are concluded: speech and song.
- They are mostly singable. They cover vast styles, genre and other elements. Poem is something that is "made or created".

- Poetry is an Art of creating Poetry. Poetry origins from Greek which means "to create or to make". It is an art of composing poems. Poetry consists of elements like imagery, diction, sound, metaphor and theme. 

I would like to give an example to differentiate Poem and Poetry:

If a Potter makes Pottery then the pots made by him is like a Poem and pottery which is an art of making pots is like Poetry.

At last we can say that Poetry is a process and Poem is it's result. Like cooking and a tasty food.
