The spelling of /d/ in this list is <d> or <dd>. The /v/ sound
is spelled <v>. Notice how the homograph read makes pairs with

revving. The contrast is between a plosive and a fricative, both
voiced but well separated in the mouth. It is not a problem for
learners. Taboo word pairs include peed/peeve. 48 of the
contrasts arise between a past tense ending and an -ive
adjective-forming derivation, such as instructed/instructive.
The program identified the contracted-form pairs we'd/we've etc,
but I have left these out for the sake of consistency. Other
interesting pairs include: The mean density value is 2.4%. The
