Minimal Pair List Diphthong /aʊ/ versus null, 41 pairs

The contrasts in this list are either from a deleted initial, such as auto/toe, a deleted final open syllable, such as mentor/meant, or from a closed syllable whose consonants permit clustering, such as calling/cling.

In the third of these cases an unstressed component may move up to acquire stress, so that the contrast is not strictly minimal, though in cases where the /ɔ/ is unstressed
the contrast is more truly minimal, such as carport/carped.

There are 69 semantic contrasts in the list, giving a semantic loading of 78%.
