Consonants /t/ versus /s/, 1352 pairs     

The spelling of /t/ is usually <t>, <te> or <tt>, but we also often see <ght> in sight. The /s/ sound is <s>, <ss>, <sce> or <ce>. I have excluded several pairs which the computer identified where the sounds are reversed, making them not strictly minimal, such as abates/abased or acts/axed.

The contrast is between a plosive and a fricative, both voiceless and close together in the mouth. The sounds are widespread in most of the world's languages, and the contrast is not a problem for learners, apart from Thais who have trouble when the sounds occur in syllable-final position.

The length of the list is mainly accounted for by 539 -s and -ed endings added to verbs ending in voiceless consonants. These are listed separately. The length is also partly accounted for by 200 occurrences of -ant versus -ance and similar pairs. These would be transcribed with final /nt/ or /ns/ clusters. Once again I have listed these separately. The interesting point is that the /ns/ cluster is effectively indistinguishable from the /nts/ cluster; the tongue cannot avoid passing through the /t/ position as it moves from /n/ to /s/. Therefore I might have included pairs with print/prints as well as print/prince, though I have not done so.

Taboo word pairs include art/arse, crapped/craps, fart/farce, pit/piss, wanked/wanks and fucked/fucks.

Interesting pairs include:

autumn awesome
dentist densest
latitude lassitude
looted lucid
mortal morsel
plaited placid
syntax tintacks
teenier senior
turpentine serpentine

The mean density value is 4.7%, but this comes down to 2.1% if we exclude the pairs arising from inflectional changes only. Also excluding those cases, the list makes 371 semantic distinctions, a loading of 61%. Including the inflectional varieties raises this loading to 82%.
