diacritically

It is unmarked diacritically since it is closer to the position of rest for the tongue.

To indicate that a glottal stop, and not a mere vowel, was intended, hamza was added diacritically to alif.

The same claim is sometimes made for Yemenite Hebrew or Temanit, which differs from other Mizrahi dialects by having a radically different vowel system, and distinguishing between different diacritically marked consonants that are pronounced identically in other dialects (for example gimel and "ghimel".)
