Hushed are the waves
washing, almost forgotten
upon morning tide
Even with the suggestion of breaking I still count 5 - 7 - 5,,, 17, though "are" or "the" are often not considered as syllables which baffles me, and breaking adds no more or no less than washing.
OK I confess maybe I messed up, but even tried "Hushed the breaking waves" and count 6 in it???

I'm just gonna quit haiku.
