关键区别：诗歌被描述为以散文或韵文的形式表达各种情感或思想的词的组合，而押韵可以被描述为一首重复相似声音的诗，通常在交替的行的末尾。

Poem is described as a composition of words in form of prose or verse that is used to express various emoti*** or ideas whereas rhyme can be described as a poem with repetition of similar sounds often at the end of alternate lines. Rhyme in poetry has been derived from its meaning in English language as an element that brings similar sounding words together. Due to the fact that rhyme as a component is most often found in lines of poems, the poems with rhyming elements in it are also known as rhymes. A poem can possess a rhyming or non rhyming form. To understand the rhymes we can c***ider the example of nursery or kindergarten poems. They are simple to understand and due to rhythmic form they are also known as nursery rhymes.

For example, one most popular nursery rhyme is-

咩，咩，害群之马

你有羊毛吗？

是的先生，是的先生

三个袋子装满了。

在这个例子中，单词“wool”和“full”听起来很相似，因此用来产生押韵效果。

Poem is a composition that is written or spoken for communicating beautiful, imaginative or elevated thoughts. Poem and rhyme both 

belong to genre of Poetry. A form of poetry known as Blank verse denotes poems which are unrhymed by definition and often favoured by Milton, Shakespeare, Wordsworth, Keats and Tennyson amongst many others.  External rhyme is the rhyming of words at the end of lines and internal rhyme means two words rhyming within the same line. Thus a poem can be distinguished from a rhyme by checking the matching up of sounds and syllables, usually at the end of lines. If the match exists, it is a rhyme otherwise a poem.

押韵是以诗歌的声音出现的。诗的声音除了押韵外，还可以是节奏的形式，也可以是头韵的形式。押韵大致可分为对联、打油诗、八度音阶和歌谣节。诗歌由意象、用词、声音、隐喻、主题等要素构成。已知最早的西方诗歌包括著名的希腊名著《伊利亚特》和《奥德赛》。当时的希腊人大多用诗歌来庆祝他们的英雄。
