Frances Karttunen: 

MOLIC-TLI elbow / codo (M), su codo (parte del cuerpo) (Z), codo (medida) (Z) [(1)Bf.10r, (4)Zp.29,160,2O2]. Z has a long vowel in the first syllable, but B specifically marks it short, and it is also short in MOLICPI-TL. Z has extended this to mean a unit of length measurement on the model of Spanish codo.
