Minimal Pair List Vowels 7 and 17, /ɔ/ versus / aʊ / 131 pairs

The /ɔ/ vowel is usually spelled <or>, <our>, and <oar>, but we also see <al> in call , <au> in sauce , <aw> in dawn and <ar> after <w> in war and water . The / aʊ / diphthong is spelled <ow> or <ou>.

This is a contrast between a long vowel and a diphthong. The starting positions are fairly close in the mouth and, although there is a difference of lip-rounding, there is potential for confusion. It is a recognised difficulty for speakers of Norwegian and perhaps some others.

Interesting pairs include:

debauch debouch
Norse nous
waterfall waterfowl
