Fricative

From Teflpedia

A fricative (/ˈfrɪkətɪv/) is a consonant sound produced by forcing air through a narrow channel made by placing two speech articulators close together.

They may be subcategorised into sibilants and non-sibilant fricatives.

The fricatives in the Standard English phonemes are /f/, /v/, /θ/ /ð/, /s/, /z/ /ʃ/ and /ʒ/
