having an extrametrical syllable at the end of one line that forms a foot with the first syllable of the next line. The term is used to describe a type of verse in sprung rhythm, Gerard Manley Hopkins's method of counting only the stressed syllables of a line. Thus, the metre of a verse is determined by feet of varying length but always having the accent on the first syllable. The third and fourth lines of Hopkins's Spring and Fall (here shown, for the sake of clarity, without Hopkins's own accent marks) are an example of rove-over: Leaves, like the things of man, you With your fresh thoughts care for, can you?
