CHICUĒXPA eight times /ocho veces (M) [(2)Tp.124]. M forms this with the regular compounding form of CHICUĒY(I). T has two variants. In one the final stem vowel is retained between stem and –PA . The other variant is like M’s but with the X weakened before -PA. See CHICUĒY(I), -PA. Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 50.
