Identical rhyme in English poetry is when the verse has identical vowel and identical onset twice in rhyming positions, most often repeating the same word:
We paused before a House that seemed A Swelling of the Ground – The Roof was scarcely visible – The Cornice – in the Ground – (Because I Could not Stop For Death by Emily Dickinson)
repeating words that sound identical but appear different such as too and two, son and sun, one and won and so on.
However, in English poetry identical rhyme is frowned upon and considered as lacking creativity, unlike in other literatures.
