Frances Karttunen: 

NENCĀYŌ-TL possessed form: -NENCĀ sustenance, what one needs to support life / mantenimiento humano (M) [(3)Cf.49r,54r]. This conventionally appears in the phrase -YŌLCĀ -NENCĀ (both possessed) with the sense 'one's daily sustenance.' The possessed form -NENCĀ contrasts with NĒNCAH 'for something to be in vain' both in vowel length and in the presence or absence of a final glottal stop. See NEM(I), -YŌ.
