Minimal Pair List Consonants /b/ versus /f/: 525 pairs
The spelling of /b/ is always either <b> or <bb>. The /f/ sound is <f> or <ff> and occasionally <ph> as in camphor .
The contrast is between a voiced plosive and a voiceless fricative. Although they are fairly close in the mouth. I have never heard of it being a problem.
One taboo word pair is buck/fuck .
Interesting pairs include
baboon buffoon
bantam phantom
barrier farrier
bellow fellow
bigger figure
binary finery
blemish Flemish
hibernate hyphenate
wobble waffle
