Does the poem Spring and Fall by Hopkins have internal rhyming?

Yes, "Spring and Fall: To a Young Child" by Gerard Manley Hopkins does have internal rhyming.

Here are a few examples:

* Stanza 1: "Márgarét are sweet— Why, alas! do they die?" (internal rhyme between "Margaret" and "sweet" and "why" and "die")

* Stanza 2: "Sórrow's spríngs áre sètt Lèss nów than thén; they wèrn áftèr thén:" (internal rhyme between "sorrow" and "spring", "set" and "less", and "then" and "after")

* Stanza 3: "Wórld enough to sèe thàt thíng I sèe:" (internal rhyme between "world" and "see", and "thing" and "see")

Internal rhyme is a key feature of Hopkins's style, adding a musicality and complexity to his poetry.
