Answer:
stanza
Explanation:
The number of lines within a stanza can change depending on the type of poem and even the type of stanza the peta wants to make. Sonnets, for example, present 4 stanzas with different numbers of lines between them. Other types of poems have a free pattern of lines that depend on the choice of the author for that theme.
The stanzas are named by the number of lines it has, so we can classify them as: couplet (2 lines), tercet (3 lines), quatrain (4 lines), cinquain (5 lines), sestet (6 lines, sometimes it's called a sexain), septet (7 lines), octave (8 lines).
