Final answer:
Stanzas in poetry are named according to the number of lines they have: a Couplet has 2 lines, a Triplet or Tercet has 3 lines, a Quatrain has 4 lines, a Quintet has 5 lines, a Sestet has 6 lines, a Septet has 7 lines, and an Octet has 8 lines.
Step-by-step explanation:
The terms for the names of stanzas based on the number of lines they contain are as follows: a Couplet has 2 lines, a Triplet or Tercet has 3 lines, a Quatrain has 4 lines, a Cinquain, Quintain, or Quintet has 5 lines, a Sextain or Sestet has 6 lines, a Septet includes 7 lines, and an Octet (sometimes called an octave) has 8 lines.
Poetic forms like sonnets use these stanza forms as part of their structure, which affects both the rhythm and the meaning that the poem conveys. The sestina is a good example of a complex poetic form that uses repetitive end words in its stanzas. The stanza length can vary, especially in free verse, where the poet has more liberty in terms of form and structure.
