ABSTRACT
Without vowels it would be very hard to communicate. Every word, and every syllable within a word, must have a vowel sound, otherwise we would not be able to say or hear words clearly at all.
If you’re thinking of possible exceptions to this, such as the second syllable in words like ‘double’, ‘chasm’ or ‘button’, then you have come across what is sometimes termed a ‘syllabic consonant’.
