LINES

Definition : a unit of language in which in a poem or a play is divided.


Example : 
[a stanza is a series of lines.]


With his own sword,
Which he did wave against my throat, I have ta'en
His head from him.
~by William Shakespeare 


the line between the lines are called lines. [the other type of lines that i was talking about.]


Significance : Like a stanza, lines separate the ideas that was given by the poet in a poem. Lines make a poem easier to read as to understand. Lines sometimes don't help much with all the imagery or the symbols of the poem but basically, lines separate the lines in a poem.
