Vowels 4 and 10, // versus /ʌ/    436 pairs      [lackluck.html]

The // vowel is spelled <a> followed by two consonants or by one consonant in a monosyllable. The /ʌ/ vowel is normally spelled <u>, but is also <o> before nasals as come or Monday and <ou> in courage and double.

Vowel 4 is short, half open and front; vowel 10 is short, half open and mid. Very few languages have quite as thick a cluster of vowels in the half-open/open zone of the mouth as English does, so this contrast is a widespread problem. It is worst for speakers of 5-vowel languages such as Italian or Swahili, but can also pose difficulties for French, Spanish, Greek, Chinese and Japanese speakers.

The taboo word pairs are bagger/bugger, cant/cunt and fact/fucked.

Interesting pairs include:

campus compass
dabble double
fanfare funfair

The mean density is 4.8%. The set makes 198 semantic contrasts giving a loading of 46%.
