Gloria Yu answered The ones I know areHaiku-- a Japanese type of Poem, consisting of 3 lines, Line 1 is 5 syllables, line 2 is 7 syllables, line 3 is 5.Acrostic-- very easy, the first letter of every line makes the word, or topic of the poem.Cinquain -- an unrhyming poem with 5 lines. Line 1 is 2 syllables. Line 2 is 4 syllables, line 3 is 6, line 4 is 8, line 5 is 2.Freeverse -- in my point of view, the easiest, because it has no set rules. It can be rhyming or not rhyming.Limerick: Should be exaggerating. Has five lines, and rhymes. Should be aabba.
