au/aw
Core Rule
au/aw represent the long vowel /ɔː/ (clearer in British English; often /ɑː/ in General American). au typically appears within words, while aw is common at word endings or before certain consonants. They function as a single vowel sound, not a blend.
Articulation Guide
Retract the tongue slightly and raise the back; lips are gently rounded, never tense. Let the airflow remain smooth and sustained. Avoid any glide toward /aʊ/.
Word Analysis
- alter: No au/aw spelling, but its /ɔː/ quality helps anchor the target sound.
- appalling: The au in appall carries /ɔː/ in the stressed syllable; length matters.
- authentic: au keeps a steady /ɔː/ before /θ/; do not shorten it.
Pitfalls
Learners often confuse au/aw with /aʊ/ as in now. Also watch for historical spellings where al + consonant or o share the same sound but different letters.
