word-final B might have been lost when it was a sonorant whereas it was preserved when
it was not.

Other major exceptions to the consonantal compatibility restrictions belong to a similar
root type in which the first and the third consonants are not identical but in a way related.
In all of the following roots, the first and the third consonants should not normally co-
occur within a root:

• 5n/"gall" • pV'thin"

• pnq "to bale out" • hps "foreleg"

• hidw "dough" • hcq "to shave"

• h>k-lb "disaffected person" • snt "to oppose"

• snd.wt "loincloth" • kip "to burn incense"

• gnh.t "star"

It is possible that at least some of these were originally (incomplete) reduplications. This
would mean that the first and the third consonants were originally identical but
underwent different developments with time.
