1276: The Vowels of 'Rhythm' (LITW 3) Jun 8, 2018

There is a rumour " 'rhythm' is the longest English word without a vowel" and disregarding the 'y', it does show the way that English-spellers view vowels. 'Rhythm' is two syllables not one, so assuming the 'y' represents the sound [ɪ], there would seem to still need to be another vowel somewhere in pronunciation to make the middle of the second vowel. This comes down to what is called 'syllabic consonants', and this can be thought of like the [ə] in words like 'the' or 'gum' (sort of). However, in words like 'rhythm' and 'column' the vowel is even shorter and less prominent, such that it it thought of as only being a byproduct of moving from one consonant to the next while still breathing out. So, while the number of syllables doesn't change, there is some truth in saying there are fewer-than-expected vowels, though certainly not zero.
