This is a very bad verse, because _a_ is dominant over _é_ and brings
about stress-shift, and the two consecutive syllables _a_ and _ver_ are
both stressed. The result is unharmonious. A syllable bearing stress and
standing immediately before the final stress is called an obstructing
syllable (_una sílaba obstruccionista_). Every effort is made by a good
poet to avoid such a cacophony. The above is a good example of one. I
have emended llegué to _llegue_ in the text.
A short verse can easily be spoken without pause, but above ten
syllables it becomes necessary for the reader to rest somewhere within
the line. The resting-place is called the caesural pause. The longer the
verse, the greater its importance. It does not prevent synalepha. The
stress immediately before the caesura must be the second most important
rhythmic stress of the verse.
