Plural of waayp "speaks, talks".
Spelled uchewayp in Mesa Grande. Also chewayp and chuuwayp per other speakers. Spelling here reflects the actual sound: lack of "u" quality in the first syllable. Could also be spelled echewayp; note the "w" causes the preceding shwa to sound like "u".
This example was provided as a third-person plural, though it sounds like it begins with a glottal stop (').
