Transitive "cleans something, cleans it up"
aahechekwarr (aahechekwarrch) in Mesa Grande.
Compare to verb hechekwar "is cleared, clean" and hechekwarr "is bald".
Based on the recorded pattern, Cuevas' plural may be aachekwarch "they clean", but this is unconfirmed.
The "a" in the last syllable sounds like it may be a long "aa", but this could also be the speaker enunciating slowly for the recording.
The "r" in this recording is clearly a single "r", despite the Mesa Grande word being "rr".
