Stops with guttural aspiration (NLD p. 697 1st edn, page 751 2nd edn)
Stops with guttural aspiration are represented by two-letter symbols, or digraphs: kȟ, pȟ, tȟ. They have no English equivalent and they are best described as a merging of the stops with the consonant ȟ. The pronunciation of stops with guttural aspiration may be somewhat challenging to master in the beginning, but the fact that they do not conflict with English phonology in any way makes them easy to hear and remember for English speakers. Stops with guttural aspiration constitute 10-12% of all stops in any given Lakota speech or text.
Example words are
kȟáŋta plum
kȟolá friend
pȟahíŋ porcupine
pȟasú nose
tȟatȟáŋka buffalo bull
tȟó to be blue.
