After Wordsworth described poetic inspiration as “the spontaneous overflow of powerful feelings” rooted in the poet’s inner emotions, which poetic form gained the most popularity during the Romantic era?

Explanation

The Romantic movement emphasized personal emotion and individual experience in poetry. Wordsworth's idea that poetry stems from a 'spontaneous overflow of powerful feelings' led to the rise in popularity of first-person lyric poems, which express the poet’s inner thoughts and emotions directly. Other forms like sonnets or political verse did not capture this personal, emotional spontaneity as effectively.
