Minimal Pair List Consonants /f/ versus /Ɵ/, 61 pairs
The /f/ sound is spelled with <f> or <ff>, and exceptionally <gh> in laugh . The /Ɵ/ sound is spelled <th> throughout.
The contrast is between a labio-dental fricative and a dental and alveolar fricative, both voiceless. The sounds are very similar and can be a source of misunderstanding even among native speakers. Novelists often replace <th> with <f> in dialogue to suggest working-class speech: "That's what I fink" or "Fings ain't wot vey used to be." David Lodge exploits the contrast in the title of his novel about the problems of increasing deafness in old age, Deaf Sentence , with its punning allusion to the familiar collocation "Death sentence", and which he admits poses a huge problem for translators.
The mean density value is 1.2%, but the true value is probably lower since a number of the <th> words in the list are unusual or obsolescent: Cathay, thane, thews, thole and withe . This suggests some support for the O'Connor conjecture that language is self-repairing. The list makes 42 semantic distinctions, a loading of 69%.
