the hiatus marks the deliberation with which the act is performed.
(4) When two accented vowels come together, the hiatus is much more
pleasing than the synalœpha; Herrera:
¡Oh yà ìsla católica potente!
But synalœpha is tolerable when the second accent does not coincide with
the end of the clause or with a necessary rhythmical accent; Herrera:
¿Qu[é á]spera condición de fiero pecho?
Quintana:
Ser[á a]lma sin amor ni sentimiento.
N.B.—In Old Spanish poetry hiatus prevailed and synalœpha was less
common. Cf. F. Hanssen, _Notas á la prosodia castellana_ (cited above).
