This is the fifteenth of the twenty-four consonant sounds in our British English phonetic chart.
A consonant is a basic speech sound in which the breath is at least partially obstructed and which can be combined with a vowel to form a syllable.
This consonant sound is found in words like shower /ʃɑʊə/, sugar /ʃʊgə/, dish /dɪʃ/.
This consonant sound is unvoiced. It is known as a fricative. Fricatives disrupt the flow of air around parts of the mouth. In this case the air is disrupted by bunching up the tongue. Its voiced counterpart is /ʒ/.
