Language teaching, like other educational activities, may employ specialized vocabulary and word use. This list is a glossary for English language learning and teaching using the communicative approach.
Vowel A sound in spoken language characterized by an open configuration of the voice tract so that there is no build-up of air pressure above the vocal cords. The Roman vowels include the letters “a”, “e”, “i”, “o”, “u” and sometimes “y”. In all languages, vowels form the nucleus of a syllable. A vowel also completes a syllable. Semivowel A sound that is much like the vowel, but is not the key (nuclear) sound in a syllable. Examples: the opening sounds in the words “yet” and “wet”. Consonant An alphabetic character which represents a sound created by a constriction or closure at one or more points along the vocal tract. Consonants form the onset or end of a syllable, or both.
