Consonants /p/ and /b/, 612 pairs     [pinbin.html]

There are no problems with spelling since /p/ is always <p> or <pp>, while /b/ is always <b> or <bb>.

There were a number of pairs where the contrast occurred twice, such as pop/bob. I have left in one or two of the more interesting ones, such as purple/burble, though I removed most such pairs, since they are not really minimal.

The difference between these sounds is small enough to be a problem for many learners, especially when the sound is final in a monosyllable. This is a recognised difficulty for German and Dutch speakers, but even native speakers of English can make mistakes in rapid speech. When the contrasts is initial, it is a known problem for Arabic speakers. (I once had an essay from an Arabic-speaking student who wrote about "the Pig Pen watch", meaning Big Ben). It may also be a problem to some extent for speakers of Indian languages which use unaspirated initial voiceless stops and Southeast Asian languages which make a phonemic contrast between aspirated and unaspirated voiceless stops.

As usual, I have included inflected forms such as ropes/robes and roped/robed even though they are not strictly minimal. See the main page for an explanation.

The contrast may be neutralised after /s/ or /z/. Thus there is hardly any difference between "the spread" and "this bread" or between "taste buds" and "taste spuds", as was cleverly exploited by the small local business selling baked potatoes in Shaftesbury.

Several taboo words occur in potentially embarrassing contrasts, such as crap/crab, peeing/being, and nipple/nibble.

Interesting pairs include:

ample amble
callipers calibres
oppressed abreast
pearly burly
plunder blunder
pullet bullet
pumpkin bumpkin
simple symbol
staple stable
