Consonants /d/ versus /f/, 402 pairs     [dinefine.html]

The spelling of /d/ in this list is <d> or <dd>. The /f/ sound is spelled <f>, <ff>, <ph> or <gh> in cough. Notice how the homograph does makes pairs with foes and fuzz and the homograph read makes pairs with reef and ref.

The contrast is between a voiced plosive and a voiceless fricative, well separated in the mouth. It is not a problem for learners.

Taboo word pairs include dart/fart and duck/fuck.

The phrase "dual fuel" has become familiar through cookers and domestic heating systems that can use electricity or gas. One pair of arguable status is handle/handful, where the /d/ in handful is elided between the other consonants. Other interesting pairs include:

carded Cardiff
cider cipher
Dallas phallus
digit fidget
doormat format
handle handful
inedible ineffable
liquidize liquefies
odysseys offices
radish raffish
tarried tariff
