Vowels 6 and 20, /ɒ/ versus /ʊə/    19 pairs      [godgourd.html]

The /ɒ/ vowel is spelled <o>. The /ʊə/ diphthong is spelled <oor> or <our>.

This contrast is between a short vowel and a diphthong. The starting positions are close and there is some potential for confusion, but there are so few minimal pairs that it is not a problem for learners.

The density value is very small at 0.76%. The pairs make 6 semantic contrasts, giving a loading of 75%, though that has no significance with such a small set.
