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 reeve and rev, and the place name Reading makes a pair 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:
