Examples
A glottal stop is made during the hold of the click; the (necessarily voiceless) click is released, and then the glottal hold is released into the vowel.
Few languages make a phonemic distinction between a word beginning with a vowel and a word beginning with a glottal stop followed by a vowel, since the distinction will generally only be audible following another word.
For example, a glottal stop does not occur in other situations in German, e.g. before a consonant or at the end of word.
For example, standard German (excluding many southern accents) and Arabic both require that a glottal stop be inserted between a word and a following, putatively vowel-initial word.
Furthermore, an apostrophe may be used to indicate a glottal stop in transliterations.
However, this glottal stop undergoes sandhi whenever followed by consonant, or more often than not (see below).
